I have plenty of tolerance. They stay off the server I'm on and I'm good. They show up and I get the hell out, find a server they aren't on. It works nicely as long as nobody suggest I play competitively.
There's no relation with overly serious players in pub servers and competetive games, which you were originally attacking.
But otherwise I understand your point. IMO pub servers = for fun. If you're there for something else, get out.
