Nevertheless, our country saw some pretty horrific deeds done in the name of religion too.
Anyway, I see your underlying point but there's something important you're leaving out (besides the fact of having to go back in time a couple hundred years to find an equivalent). Witch trials went on for a long time in Europe. By comparison, they ended here almost as soon as they began, when people began to notice that the accusers had reasons other than religious ones for their accusations, and they felt FREE to point that out. What's more, they were actually heard. What were the chances of being "heard" in Europe at that time, if you weren't a noble or a landowner?
By the end of the witch-trial period, laws had been passed disallowing "spirit evidence" against defendants in court.
Abuses happen everywhere, but a rights-based culture tends to self-correct a lot faster.
