I prefer the Gulag, personally. It's pretty difficult to spread your cancerously stupid ideas from the middle of Siberia. Or if you're dead.
The communists got a lot of things wrong, but putting (what they considered) the refuse of society to work and getting some utility out of them was not one of them. They simply put people in the Gulags for completely the wrong reasons, which is repugnant, but the system itself was quite sound for its time. Our reasons are materially and morally superior, so we needn't worry about that.
They thought wrong. Our methods for reaching the truth are empirically superior.
Every political system that committed mass murder had their reasons "materially and morally superior." How is yours different?
...
No, it's not a rhetorical question.
They can't make our lives harder when they cease to exist. Look at what happened to the imbecilic toaster huggers during the toaster uprising. Where are they now?
They were killed - not by the geth, but by quarians who shared your philosophy of killing those who disagreed with them. This kinda vindicated and backfired on them at the same time: the geth did take up arms - but not in some inexplicable droid rage, or because they were discontent with being slaves, but to defend their quarian masters - from other quarians who tried to destroy both of them for the crime of existence and differing opinions, respectively. The latter group managed to prove their point of the geth being dangerous by antagonizing them to the point where the only reasonable thing to do (and as even you admit it, the geth are perfectly capable of reason) was to be dangerous - towards said genocidal quarians, that is.
Of course, the war taken took its turns in a way that the only survivors were from this genocidal faction, so now they are free to espouse their views about the geth and forget about little inconvenient facts like this. They proved that they are right by silencing voice that would question their "truth." There is no doubt about it if there is no one to doubt it, right?
They can have fun doing that from the Gulag. Or from the medical experimentation table. Or from the weapons testing range. We'll get rid of the weak and the stupid, and their noble sacrifices will contribute to the continued progress and pleasure of the superior at the same time.
"Noble sacrifice" implies that those weak and stupid will approve your system, which is highly unlikely, to say the least. (Also, how could be someone stupid if they approve your ideas?) "Genocide" and "ideological cleansing" would be more accurate.
It's also suspiciously convenient that the proper order of the world just happen to see YOU at the top of the food chain, and everyone you dislike dead.
Plenty of Geologists at the time accepted Wegner's theory. Not a majority obviously (mostly due to petulance against the manner in which he presented his theories rather than their actual content), but a not insignificant minority of the scientific community saw the plausibility of his work despite its flaws. Moreover, you are conflating my ideology with crushing all dissent, empirically based and otherwise, when it is nothing of the sort. Great ideas usually come from elite, minority thinkers (the Master Race, if you will), and this brilliance should be vehemently encouraged. There is simply no reason to give any credit to ideas that do not even attempt to have a basis in empirical fact (such as creationism, or toaster hugging), nor any reason to keep around the inferiors who espouse such flawed ideologies as anything other than labor or test material.
Wegener was a meteorologist. An outsider, not some geologist wunderkind. On the other hand, Schiaparelli and Blondlot were accomplished scientists in their own fields, but now most remembered for their completely imaginary Mars channels and N-rays. It is easy to judge in hindsight which idea was great, but you cannot predict which new, controversial idea will turn out to be good. The only way to identify the member of your "master race" is to watch them make their great discovery, then add them to the group one by one. Your "master race" concept has no predictive value.
The pillar of empiricism is always accepting that your idea could be incorrect or subject to improvement, and to always be striving for more information in search of the truth.
It's a great idea, in theory. Problem for you, the sign of its working is that from time to time, you are proven wrong and have to revise your world model. If it doesn't happen with you regularly, then you don't use it properly. Considering that you vehemently refuse to even try to gain new information by understanding other people's reasons for coming to their beliefs (even if it only amounts to "he is schizophrenic and was surrounded by false information in his entire life")...
That doesn't mean tolerating ideas that are blatantly silly and incorrect to anyone who has even a tenuous grasp of the subject matter.
If you don't tolerate them, why should they tolerate you? And by your terms, non-tolerance means killing or worse. The only resolution to a difference in opinions would be a fight to the death. The only objective truth this can reveal is who is better at killing. And weapons don't care if the person they kill is right or wrong. Do you really want to live in this world? Or do you imagined that your "superior truth" can come into power by making only superior firepower matter?
When have I ever done that? No argument is too uncomfortable to me. I don't find winning to cause discomfort. Now, I may stop engaging in an "argument" when I have unequivocally defeated my opponent and said opponent Can't Handle the Truth, continuing to regurgitate nonsense that has already been thoroughly refuted in a futile attempt at keeping face, but that is entirely different. No use wasting time any more time on those who inisist on maintaining a faith based belief, and do not wish to see reason for fear of the intellectual challenge it poses, at least not beyond what is necessary to publicly humiliate them. They will simply find themselves in the Gulag or on the operating table in time.
Yeees, you didn't burn your hand, you can just look at horseshoes very quickly!
EDIT: It's easy to declare yourself right when the only judge of that is yourself. That's why we have things like peer-review and control groups in actual science.
Know who else does that? Theocracies. Great ideology there. Space Iran is exactly the type of society I want to live in.
You do want to live in a totalitarian system. You just want to be part of the regime.
I, for one, want to live in a system of equality, where I am free to tell my opinions without the fear of being put into a death camp. Where I can tell my opinions to anyone who would listen to (although not neccessarily heed) them, and in exchange, I'm willing to listen (if not neccessarily agree with) the opinions of everyone who wants to tell them. I want to live in a world where truth is accepted by consensus, not where a single person or a small cabal is destroying everyone who disagrees with them. Not even if that person would be me.
