Like I said, I can't force you to do anything... but for you partners/points sakes you need to consider other peoples feelings. Yes people can overreact in ranked games, but there doing it for competitive reasons. If you don't care so much about points/winning, then maybe ranked games aren't for you...
cavs was being an ass (ranting and all), but truth be told he was right. I can't tell you what to do, but it's best in that set-up to yak night one and never cc hunter as mafia. good luck in future game :D
