I say: Do it.
The siccness used to be a place where there was no "too far". You said/did something and accepted the consequences. There were no apologies, no stomping off in a huff, none of this modern-day cry baby bullshit. You gave shit, and you took shit. If you couldn't take it, that was the sign it was time to leave.
That's a big part of what changed around here. It used to be like a fraternity, where you earned being included after a fair time of being funny, or taking other peoples shit, or contributing something to the group. Now it's a gang of new folks that cant take the heat so they lash out or cry, and a gang of OG's have become overly complacent.
So I say do it. Do it, and don't apologize for it when he gets mad. Then do something even more foul. Because that's why this is the "siccness" not the "niceness" or "politically-correctness" those rules don't apply here.
