I am of the opinion that as long as we are stating facts, we can't really lose in the debate.

It's also important that we address behaviors when we criticize and not someone. If I was to say @soandso is an asshole, that says nothing about the behavior, and thus fixes or addresses nothing.

If we talk facts, and we catch flags, the real "loser" is the person/user who had to resort to flagging because he/she ran out of arguments.... and in that case, I would take the flag as an honor badge.
