The way this sounds is that you are more concerned about politics as in people who take party positions and may feel excluded as a group when the majority of the community takes a different position. This is a slightly different issue i.e. party politics, and I think it is fine/a good thing, but it is also important to distinguish the two. This should essentially be under the same umbrella as personal attacks, as they are essentially the same thing.
Anyway, I like the non-political week. Anyway... that's just my two pence...

I'm not aware of any other recent significant bans, so I don't know what user samstave means by ``They were like "Oh! BAM" A ban on /r/this and that.''
