no, I want to talk about offense, not just question, there is no doubt that you can question, no one is going to bite your head off if you ask
well the way Carlin sees it, the religion he was mocking caused the death of thousands of innocent people, people were burned alive in its name and it is not backed by real evidence and witnesses. Bush said God asked him to wage the war on Iraq masalan... for these reasons he saw religion as something harmful and he disliked it...
maybe not talking about it and not offending it would be a way to let these things slide without consequences...
