It's not the community. Honestly, this stuff happens, but mostly everyone can spot the douchebag being the douchebag right away, they are usually the ones who think they are pro and don't want anyone slowing them down, which is ironic since they are the ones who tend to also wipe most in fights. The nicer players are the ones who are good players from my experience. Either way from the op screenshot, just from being unpleasant I'd kick him and let him go find a g group of people who never make "stupid" choices.
