Because you were wrong about something? 
I was only wrong if we were looking at the Extended Cut. You said I was stuck in the original endings and then said your whole theory was about the original endings.
It's not an interpretation. I'm taking the raw data as is. It is objectively not narrated in past tense. This is a fact. Not an opinion. A grammatical fact.
It's also irrelevant, as I explained.
What you're presenting is the Bad Writing Theory, which is a valid conclusion. However, if that's how you feel there is nothing further to discuss as attributing it to bad writing effectively negates any discussion about the in-game events. It's just a hot sloppy messs that doesn't need to held to any scrutiny. It's the equivalent of saying the devil buried the bones of the dinosaurs in a debate about the age of the earth between a Christian literalist and a Christian scientist. Essentially saying carbon dating and the like isn't reliable because supernatural forces made or altered the world in a inconsistent fashion. It's a supernatural act that can't be intellectually debated on the merits of science. Even your stance of knowing the writers' intent is tantamount to person knowing that some god hates it when gays get a legal document of marriage. Such "inside knowledge" is just a belief. There is no factual data. Again, there is no debate to be had.
The in-game events are the evidence of bad writing. This isn't a theory, but is in demonstrable fact. Holding it to scrutiny is how we get to that conclusion. It looks at everything literally rather than making things up, even reasonable things, to patch the broken narrative. It can be intellectually debated on the merits of writer's craft. I take a stance on writer intent on what is clearly presented. You are taking a stance on writer intent based on supposedly hidden meanings.
Between your wild imaginings, animosity towards disagreement, and hate of Christianity, I'd think you were Gothpunkboy but you've made more sense.
No, go on YouTube and watch it. Or play it yourself if you have the save. The technology part is a direct response to Shepard seeking clarity on what the Kid says about synthetics being affected. He even includes Shepard's synthetics as being included in the synthetics in question in that very opening statement. Then Shepard asks, in response, "What exactly will happen. The Kid then clarifies it. It says tech to rely on will be damaged, but it'll be nothing that you can't fix. I am the Official Lore Master of Mass Effect™. I know my stuff. If Synthetics, like Shepard's, are affected how is it Kasumi does not die? Her grey box would be wrecked and she's end up in a coma at best. Oh, right, you're a Bad Writing Theorist so nothing has to make sense.
Did it and it says what I said it says. He says "all Synthetics will be targeted." When Shepard asks for clarification, he says technology will be "affected" and "there will still be losses." We don't know what that means or how broad ranging it is just from these lines. We have to look at other things, and I mentioned them in the earlier post. The clear message is that the Geth are dead in Destroy. You can stick your fingers in your years and yell "La la la" all you want, but that's what the game is telling you.
How do you make that statement about Kasumi? Do you know how the Graybox works? I just remember it being a memory storage device, not something required for brain functions.
Yet neither you nor any other person on this entire forum could refute me. All you do is deny the objective facts and insert you beliefs in as if they were facts. The cold hard fact is it's never said the Geth would be destroyed, they are never seen destroyed, they are never said to be destroyed afterwards and the end game cutscene only shows synthesized material affected. These are the objective facts. Not my opinion or belief. Facts. Show me where I'm wrong.
I don't need to refute every wild claim somebody invents. You have to support your claim. All I need to do is call it into question or present more reasonable alternatives.
To your credit, here you prove you're not Gothpunkboy. You need it shown or told to you explicitly rather than just implied, which is what he usually uses to criticize those who disagree with him. Eww, I feel dirty now...
Anyway, all you've said there is that you're taking absence of evidence as evidence of absence, which doesn't work here. You're right that you're not explicitly shown or told "the Geth are dead" but there are several things that point to that being the case.
Why? I does not matter, but I'll give you my educated guess on the subject. Because the entire point is to make Blue and Green look better. Who would ever bother with them if they didn't leave a bad taste in your mouth in Red? I fully believe they want people to have the impression that the Geth somehow died via magic. They already put the seed in your mind during the vanilla cut. See, that is a belief on my part. I can't prove their intent here. However, I can prove that there are no instances in the game depicting or even saying the Geth are destroyed. For that reason I don't have to answer why there is no destroy Geth slide. There are no facts to back up your assumption. The why is ultimately irrelevant. The facts are the facts with or without a why.
And it's not silly. If the lack of inclusion in a slide equates to the extinction of a species then all those other races are extinct in every ending no matter what. However, the belief that a lack of slide equates to extinction is a belief. It's not a fact. If Bioware decided in the next trilogy to go back to the Milky Way and they picked Destroy as the canon ending they could use the exact argument I make for the Geth being around and there would be nothing you or anyone could come up with to invalidate it. your entire argument is based on the belief that you know the writers intent. The fact that the writers can prove there intent at any time by keeping the Geth around demonstrates how your argument is weak.
Out of curiosity, what makes that guess educated? That's an argument after the fact, as you don't see the scenes at the time of the choice. This is the same issue with people arguing about the explosion of the Relays. Even if we accept the argument about a different kind of explosion, that's only seen after the choice is made and that by the player, not the character. When the Catalyst says "it will also destroy the Mass Relays," all we have to go off of is Arrival, which makes using the Crucible unacceptable to both character and player. It's a known event even if Shepard didn't do it. But oops, Shepard apparently forgot about that.
I do have evidence, but you choose to ignore it because it implies my claim rather than explicitly state it.
So are you saying EDI is alive too? They don't show her dying or say she died. She is just absent from other scenes.
The Geth being in a later game would only prove the intent of the creators of that game, not that of the creators of ME3.
