Put Carlin's stand up aside. Looking at that quote i believe he is right. He has every right to question that choice INTELLECTUALLY. Ya3ne 23od 2eddeme w ne2eshne. Not only does he have to do it intellectually but he also has to do it respectfully.
You can't debate someone about his beliefs (which he holds sacred and dear) while making a mockery of everything

. That is no way to debate. That is only unprofessional, childish, and shows an extreme lack of intellectual ability. Byotla3 wa7ad 7afezlo kam kelme w nafakh sedro w jeye bado yetshatar
Yes sarcasm can be used

but only when the other side shows to be lacking of any debate ethics or capabilities allowing him to debate. But even sarcasm has certain limits.
Long story short: Question me all you want. But do so logically, respectfully, and thoroughly, and I should be expected to do the same. Do that and you will earn my undying respect regardless of who you are.
P.S: The title should be changed

Change offend into question
