Howcome christians in america have problems with evolution or stem cell research but christians in Europe?

i'm not sure but i think it has to do with how it's done. It comes from aborted babies, which abortion and pre-marital is considered wrong, are the supply of stem cells. Though the fact that the technology is avalible, the means by which it's done goes against 'morals'. That is why christians are against it, i feel.
