An actual atheist doesn’t need to address the existence of God. This is in contrast to those evangelical anti-God fanatics who > BELIEVE < it’s their mission in life to spread a gospel of disbelief...which is really just a religion that claims not to be a religion.
Yes, there is a difference between a real atheist and those who are just anti-Christian.
Real atheists, while I may disagree with them, tend to be nice people who really don’t have a problem with Christians. It’s the ones who are vehemently anti-Christian, that are the problem, for example, they always seem to want to defend Muslims.
