Terrible things have been and are still been done in the name of religion, so I guess I can’t blame you for hating it. I also totally agree religion has no place in politics.
I think the best any of us can do is play the long game and educate people without insulting them. Calling their religion a fairy tail - even if that’s what you strongly believe, will just make them defensive, dig their heels in and refuse to hear what you have to say. You might even give them the wrong idea about what Athiesm means.
There will be eventually be enough people in the right places to be abe to say enough is enough and pass legislation to remove the religious aspect of the laws of the county they are in.
I don’t know. I’ll look it up.
