I think Atheists Deep Down Have More of a Problem with Christianity than the Idea of a Universal Entity?

There are multiple posts here basically about Christians VS. Atheists. I think Atheists tend to forget that Jews, Muslims, Hindus, Sikhs, Budhists and so on, also believe in God; but Atheists seem to not have a problem with the lifestyles and ideologies of these groups of people. I think many Atheists just have a problem with the aggressive corporation of Christianity. May I remind Atheists, however, that Christianity is pretty much the only religion that openly solicites; Catholicism does not believe in solicitation or profiting and even frowns upon those who are judgmental and overzealous.
