I already commented on this on Twitter, and on G+. Here's a repost of my comments on G+:
Hilarious. But this has actually been going on in occultism for a long time.
Remember, 90% of occultism is crap, 90% of occultist are posers who do nothing. There's no better mix than SJWs, posing, and crap; they're all natural bonds to each other.
Amusingly this has even had an effect in RPGs; consider Blue Rose designer Steve Kenson, who is married to Christopher Penczak, a highly successful writer of utter garbage books on magic and witchcraft. Kenson is himself a 'wiccan priest', or was calling himself that a while back anyways.
But I'm not talking about Blue Rose here; rather Shadowrun. From some Shadowrun fans I've talked to, they attributed Kenson with utterly wrecking the previously careful balance in Shadowrun's magic system between Hermetic and Shamanic magic (note: no idea if this was later repaired in subsequent editions; I heard this back when 3e Shadowrun was the contemporary one). Why did he do this? Because Kenson's real-life belief was that obviously Shamanic magic had to be more powerful because it was based on "nature" and "inuition/feelings" and that must be more powerful than the 'intellectual' hermetic magic. Note: real shamanism isn't really based on either of these thing any more than real hermetic magic, but that's an idea that most New-age types have embraced, where "nature" translates to 300lb women with oxygen tanks calling themselves Earth Goddesses because reasons, and where "feeling and intuition" translates into "I don't actually have to do any hard work, study, or even produce any kind of results whatsoever, I can just call myself a wiccan high priest and I am one because I FEEL that way".
Anyways, the hilarious "I'm more legit ancient primitive witchcraft than you" OP material above is absurdly wrong. Magical practices originated spontaneously in pretty well every culture; they're based on observations of reality and the human condition.
And since these observations became more profound in more advanced cultures, the 'technology' of magic became more effective the more advanced a culture became (symbols could become more complex, methods of connecting to altered states and the quality of insights derived therefrom more sophisticated, changes in consciousness more advanced, ability to effect change in the world more notable - and of course, the philosophy and the 'hard sciences' that branched off from magic became more culture-changing).
