I admit I don't know much about the time of the Inquisition itself. All I've heard over my lifetime is stories about people supposedly being tortured for things like heresy and apostasy and not being faithful enough to the Catholic church. But, some Catholics, and I guess maybe some historical scholars, will say that the Inquisition is often misrepresented or "blown way out of proportions. Or, as I said in the title, some believe it is something like a smear campaign against the Catholic church made to make them look as awful as possible.
