Allow bigotry to fester in the thread for extended periods of time

I know this will be a controversial opinion but I just don't see this being a big deal. Those comments inevitably get downvoted and kicked to the bottom of the list, and if you expand a comment that's -10 karma you probably know what you're getting into. I created and modded a sub that now has over 2mil subs and never once have I locked a thread (granted, it's one that's non political but we got our fair share of weirdly bigoted comments)
