> I don't really care about the religious aspect

I certainly do!

I'm a paying supporter of the Freedom From Religion Foundation, The Satanic Temple (it has nothing to do with satanism), and even the Friendly Atheist Podcast (which is just a podcast, unlike the first two). If I donated thinking I was helping families who couldn't get their kids to school or to after-school events and then found out that there was a religious org behind the commercials, I would be furious.

You can have and practice your religion. But bad actors have been using religion as an excuse for persecution and as a means of control in the USA for decades. I'm outraged to learn that they were manipulating people in this manner.
