I’m all for it, but I don’t see how that would pass constitutional muster. I’m a lawyer, but not a constitutional law expert by any means, so maybe it’s possible to narrowly tailor a law that would work.
My concern is that anything predicated on preaching “hate” could be used against Christians later. There are secularists who truly cannot see any difference between a mosque and the local Baptist, Methodist, or Catholic congregation.
Typically they are extremist Atheists. They are less obnoxious than Islamics overall, at the moment, but when in political power in the 20th Century, they killed many tens of millions.
