Because they don't have to fear using real world analogs like black/muslim/gay/whatever, they go on rather freely wuith their opinions. Those opinions reveal the depth of indoctrination that the liberal system has warped them. It is all feelings based with absolutely no regard for consequense of action. None of it is thought through in the slightest. And they come down on the side of the Empire every time, casting Ulfric literally as Hitler and praising the Empire/Thalmor for attempting to wipe out Talos worship to bring 'Unity' to the continent.
It's almost funny if it wouldn't be so sad -- I've had similar discussions with some others. They'll say "Ulfric says 'Skyrim for the Nords'", so he's a racist. And I point out that he doesn't actually kick out other people -- he just doesn't trust them. And in contrast, the Thalmor actually
kidnap and drag off to torture anyone who varies from their religious orthodoxy. But to those people, slightly intolerant words are worse than horrible action. And part of that is also because they don't think religious freedom is important, so if a few dissenters get dragged off and never seen again, it's no great loss.
Funny how well the politics of that game mirror what we're living right now.
