Ah thanks for clarifying. Well all things being equal, I would miss sorting by controversial for the races I don't have horses in and I'd hate for all of our popcorn to get stale.
Sometimes, I just like to sort by controversial. Ignoring things you don't like or disagree with is usually enough, other times it's good to engage and challenge a different point of view, and sometimes a down vote is all the engagement you should give some people while showing solidarity with your community. I think we should have them and leave it to the communities to decide whether they want to implement it or not.
