Is it the beliefs?
Can you imagine a religious organization that an atheist would find problem-free if only they had the right beliefs? Why or why not?
The dogmatism?
Since you’re asking, I suppose you’re positing that some forms of dogmatism are good? I would like to hear some of your thoughts on what good dogmatism looks like. Otherwise, why would you ask if dogmatism is a problem?
The epistemology?
Again, I’m confused by your question. Religions don’t have a single unified epistemology. What are you asking and what do you posit or conjecture?
If you want people to put effort into talking to you, you need to reciprocate, or they will block you and move on.
