I do understand that. Theism and atheism are pretty much perpendicular to the issue of religion. There are many theistic religions, many atheistic religions, many irreligious theistic beliefs, and many irreligious atheistic beliefs. Though fewer irreligious people on both sides of the theism debate than I think most are willing to admit. For example any atheist who watches Andrew Tate's videos is not, I think, an atheist or irreligious.
