::::So much for my arguing without re-reading the article. The article says "why the relentless focus on witchcraft in the Inquisition when this was not a major fault of the Inquisition?" There may have been faults with the Inquisition and heresy but witchcraft was not a major problem. The church, basically, never believed in witchcraft. Joan was tried for heresy though the English thought she was a witch. The latter couldn't be helped. The heresy trial had been held. 

 ::::Not a strawdog when the opposition is saying that witchcraft is a major problem. It's probably more of a fallacy to say "the Inquisition killed a lot of people for heresy which was just (non-existent) "freedom of speech" and BTW killed a lot of witches too (and we don't believe in witches anymore, regardless of your answers about heresy)."
