Is being a theist immoral in your opinion?

[The Industrial Atheist]

I would say that the belief in a god itself isn't immoral at all, just a belief that isn't factually justified.

The problem comes when you start applying morals that originated thousands of years ago, and may not have even been exceptionally great morals then.

When it leads to for instance persecution of gay and trans people and unhealthy sexual repression, I don't believe it's moral to perpetuate such ideas.
