I don't like oppression. I don't mages oppressing mundanes and I don't like mundanes oppressing mages. Nobles oppressing the peasantry also doesn't rank very highly on my list of favorite things. So yeah, I'm not in favor of mage supremacism of any kind. It's wrong, it's ugly and it's already been shown to not work that well in Thedas. Mages aren't inherently better leaders then normal people. Their just more powerful, and having more physical power then most other people doesn't make you destined to lead. If that were case then jocks and gun-nuts would be the emperors of the world.
Also, and I hope what I'm about to say doesn't come off as an attack on some of the people in the forum, I think that some of the people here who are in favor of mage supremacism aren't seeing things from the perspectives of the ovcerwhelming majority of people who would be slaves or second-class citizens in this type of governance. You seriously can't believe that you would be ok with living in a society that would outright deny you the ability to seek political power or equal rights just because you can't shoot lightning from your finger tips.

Supremacy isn't about them being better leaders or better people, but simply the better creature. Would not a soldier find his job easier if he could "shoot lightning from his fingertips"? Wouldn't it be simpler for a smith if he could produce his own flame?
As far as a mage-supremacist society being innately oppressive - just because Tevinter is oppressive of mundanes does not mean all such societies would be the same. Some could see it as their duty to shepherd the more unfortunate, taking pity upon them.

And jocks and gun-nuts... really? Would that not be the intellectuals and philosophers? Not only would they be more likely to support such a society, but actually be able to create it. I, for one would support a great Philosopher-King.
