Believing in some deity is also ok, people can have their thoughts, as long as it does not harm others. A lot of people believing in some form of god, get solace out of it, so if it is, what they need to get by in this shitty world, good for them. Not all delusions are harmful.
What is not ok, is taking part in and enabling evil religious systems, and using those beliefs as an excuse for hatred, discrimination, oppression and even war. The religious folks following the actual teachings of their religions is usually fine, as those tend to be pretty good (help others, love everyone and do not hate, etc.). Also a drastic contrast to the other, fundamentalist sides doing the opposite, cherrypicking what suits them out of the beliefs, and pretending their religion justifies their evil actions.
(And I am an atheist myself, if that matters, for the context.)
