Sure, if that’s your rebuttal and your willing to accept millions, then yea some people will of course blame religion in cases where it’s not at fault.

The inquisition for example gets marginally worse treatment than it deserves. While they did torture many innocent people to death they were sometimes used by others as a means of murder. The death total wasn’t 10’s of millions either. Hell they even regularly let innocent people go

On the other hand some significantly underestimate these evils by insisting on hard evidence of each individual death. Which of course fails when paperwork was lost or was never created, people died from the torture before they could be burned etc.
