Lox, where's the concluding lines where you [and Tommy Tiernan] unequivocably say that what you wrote/said was hateful bigotry? Even if your purpose is to have a "teachable moment", in my opinion, the fact that you abhor such vile comments needs to be explicitly indicated afterwards.   

Even with a clear, unequivocable concluding statement at the conclusion of that tirade, I don't approve of those words.Nor do I approve of that tactic because bigoted people are liable to hear you expressing and reinforcing their hateful beliefs and not
'get' any statement denouncing that bigotry even if such statements are clearly made.

Furthermore, I don't find those examples either funny or witty. (I'm speaking here of your words and the words Tiernan said which-I believe-rightly got him into trouble).
