I wonder if there were gonna be any laughs from audience if she said "Jews can suck it" or "Allah can suck it"..
I´m sure there would have been laughs, though not necessarily from the same persons.
I have always found it reasonable to criticize the own crowd (own country, own culture, etc.) more directly than the others.
That said, I personally can´t detect anything funny or profoundly critical in saying "X can suck it", no matter which or whose god it is about.
Now, laughs can not be censored, and what you find funny does not necessarily allow conclusions on your stances. Laughter is a spontaneous expression of emotions, and not an intellectual statement.
I can imagine, though, that open statements (no matter how deep or superficial) against something that you have always felt had a restrictive impact on your society and your own life are emotionally perceived as liberating. Whilst, for example, criticism of gods that don´t play any role in your upbringing, your culture and your society and therefore have never affected you do not trigger your emotions as much.
Liberal secular double standard anyone??
Well, if you insist on making laughter an intellectual statement...
I´m sure you don´t want the tenets of non-Christian religions to be legislated in your country, and, by the same token, this could be called a religious conservative double standard.
I don´t see much point in making great efforts in discrediting the person you disagree with. This seems to be one of your favourite approaches, and I just don´t think it helps your case.
