I am an atheist and definitely care a ton about religion. Because what people believe highly influences their actions. A mind that can believe things without good reason or evidence can believe anything. Often these things are nasty, awful things. People then promote these things in government and society, and because they are couched in 'religion' get some sort of exemption from criticism at large. Is there anything you COULDN'T believe based on faith? If i do not need to provide evidence, is there anything i couldn't deeply hold and promote, that is offensive and problematic to a society? If i don't need to provide evidence, how can you question me when my supreme being has told me that men are better than woman, that people of my religion are better than others, that cis people are better than lgbtq+ people. That white people are better than people of color. It's my supreme being, i don't have to prove him to you. "It's true for me", and you need to respect me for it.
That is just wrong.
