The thing is, it doesn't really matter. If people were sitting around making snide, off-the-point attacks against the greek pantheon, viking mythology or Zoroastrians, nobody would give a shit. We moved one from those religions long ago.
We're in the process of moving on from Christianity just about everywhere besides the US, so to us non Americans, christianity is basically a non issue. It's something we can take the piss out of without really giving a shit if we're convincing anyone or not; it's for our benefit.
You wouldn't go out of your way to respect the beliefs of someone who believed heart and soul that the contents of Lord of the Rings were factual, neither do I have any respect for a Judean zombie lord or a four armed elephant god, it's all the same to me. It's all the same to anyone unless they are raised to positively discriminate their particularly cultures current folklore of choice.
Religion is as religion was: temporary cults that cling onto the gaps in people's education to survive long enough to fill the pockets of the clergy. Simple as that.
"Is there a god?" is not a serious question, so it does not deserve serious answers, it is comic fodder, nothing more.
