And yes, I know people will say block keywords and communities, but people don't understand some communities have rules and people must follow them.
I'd be interested in seeing a politicaldiscussions community that would allow for that. I just don't have the time or energy to mod something like that or create and maintain a set of rules that would keep the discussions fair. I'd be hard pressed to find a way to prevent brigading and encourage positive discourse, even where I disagree.
