Wow, something that happened 800 odd years ago ... I bet that really has an impact on the current student body.
In all seriousness, anyone who tries to definitively answer this kind of question isn't going to get anywhere. As has already been pointed out, what is seen as 'conservative' by some doesn't necessarily apply universally, and just because a college or group is outwardly 'conservative' in some respects that does not mean it is in others.
E.g. I go to a stereotypically 'conservative' Oxford college but in reality this just means we have formal hall more often than some, get our money's worth out of silly gowns and indulge in a couple of light-hearted (if rather odd) traditions. Politically/socially the current study body is by no means Conservative/conservative, and in fact being the former will earn you a hefty amount of (generally) jovial stick.
So basically this is another pointless thread that's just going to wind people up. Well done.
