Need help.............

Who said something sexist? if you mean what i said,i was talking about people who atomatically think the worst about satanists.

So the first thing you need to understand is that there are roughly three types of Satanist; Atheistic, Theistic and Casual. Atheistic (mostly LaVeyan) satanists practice a hedonistic philosophy, where Satan is regarded as a metaphor for indulging the selfish 'nature' of humanity. They don't tend to practice magic as rule, and would certainly not threaten summoning a being they don't actually believe exists.

Theistic satanists regard Satan as a being to be worshiped, sometimes under another name or title, Lucifer for example. They would be equally unlikely to threaten summoning Satan, as it would be akin to a Christian saying they're going to conjure God to smite you down; overzealous at best, blasphemous at worst.

Finally, and most likely in my opinion, are casual Satanists, which is to say, not really satanists at all. These are mainly grungy teenage types who burn black candles in their room and listen to heavy metal, a stereotype to be sure, but quite often accurate in my experience. They have very little understanding of Satanism in any form, and base their practice around (mostly incorrect) common knowledge or pop culture, claiming to be a Satanist to shock others.

So basically, your friend's Dad is probably either deranged or lying. Though I would tend towards deranged if he's spouting nonsense about 'having power over witches'.
