You almost have to believe in evolution to be an atheist, and everybody who’s been following the discussion over the last few decades knows by now that evolution is a bunch of bullshit. The biggest group of people proportionally who don’t believe in evolution is probably mathematicians and not Christians; the doctrine is not compatible with modern mathematics and probability theory.
It is quite compatible. It is mainly incompatible to those who do not understand probability. But the largest group of people who accept natural selection are probably Christians, since most don't have a problem with it.
