Do theists people not understand just “not believing in god/gods”?

I don’t understand why theists try to compete with atheists. They don’t understand that just because we don’t believe in god, it doesn’t mean we don’t support the positive teachings of some religions. Theists think that just because we don’t believe in their god it becomes we don’t believe in all their religions values.

People are able to not believe in the religion but still fallow the values, it’s not a hard concept.

Every culture has its goods and bads.
