It appears to me that those who are not particularly religious (i.e more than 50% of westerners, possibly fewer elsewhere) have no particular view on this question. But fervently religious people are similarly hissing toward atheists (and even agnostics) as others are toward gay people, those who dress in unorthodox ways, males with long hair, etc., etc. It is to them a deep affront that someone openly refuses to conform, or even pay lip service. In my experience, many Muslim people divide the non-Muslim world into three categories: 1. non-muslim monotheistic people, 2. non-Muslim believers in more than one god (e.g. Hindus), and 3. those who pointedly have no religion (i.e. primarily atheists) - all in order of increasing disapproval. I think some strongly conformist Christians do not see things very differently and I would agree with those who have said the religious (Christians) are often surprisingly ignorant of what the Bible (including the New Testament) actually says. Not long ago I earned the vitriol of an American (typically overtly Christian) when I pointed out that nowhere in the scripture does it say that Jesus claimed to be God (son of maybe, but not God or a god) nor that his mother was a virgin. At first it was angry protest time, but when I could not be disproved (frantic search on the internet drawing a blank) I became dispised/hated. On the other hand, I know quite a few people of Christian, Muslim and Hindu faiths who are very tolerant of my agnostic position and show practically no tendendency to question/challenge it - at least no more than I (rarely) gently rib them about their faith (the difference naturally comes up very occasdionally in conversation).
