The fact that your facebook friend is an asshole about [clinton or sanders] or that you formerly favorite blogger is a bit of a jerk about the primary doesn't matter. I mean, feel free to like or hate people who are being assholes, but there's this weird notion that OH MY GOD COMPETITIVE POLITICS IS COMPETITIVE and that we all have to hug it out or something. Your spats on the internet really aren't going to impact the outcome. If your friend is a jerk, well, sorry your friend is a jerk, but it doesn't really matter aside from the personal.
