This comment is slightly off-topic, but...

I don't see much way to enforce this though, as it's a tragedy of the commons. My best guess is to persuade enough people to just reflexively downvote anything to do with object-level politics or gender (including posts masquerading as meta-level).

I just reflexively downvote anything which encourages reflexive and automatic downvoting of any pattern-matching filter. Oh wait, I can't downvote myself.

(note: I don't actually do this. I just really think it's a very silly thing to do to reflexively downvote for any broad subject. Downvote trolls and bad comments, not topics you don't like.)
