There probably are witches and wizards hanging out on CF forums.
They would be the ones saying magic/sorcery etc is ok. I mean witches and wizards aren't only story book characters. They actually are real and highly involved in the occult.
They just appear like ordinary people but practices their witchcraft etc in secret, of course they not going to tell you off the bat.
God does teach us things but they generally actually line up with His word in the Bible, and also, he doesn't want us to go after other gods and idols and sorcery etc. Thats clear in the Bible too. Not because he doesn't want us to have knowledge or anything like that, its because we are to be singleminded for Him. All that supernatural stuff, and there is a lot thats out there, only good things can come from Him above.
When you mess with things below, thats when you get in trouble - and that's where you need discernment. If you just think all spiritual things and paranormal stuff is godly, well you have another think coming.
