This person isn't using recognizable Wicca anyway. Wicca is VERY big on the gender binary, and the altar in the "altar tour" video has the seven-pointed star of Feri-tradition paganism, in which there are seven archetypes (still including "father," "mother," and "maiden," mind), which this person describes as "much more gender-balanced." (I believe it. Feri seems to be the initiatory tradition -- like Wicca, you have to be initiated somehow -- that LGBT folks flock to.) In Wicca as cobbled together from other religions by Gerald Gardner in the 1940s, there is a God and a Goddess, and there is a lot of cishet going on.
And of course, on the altar, this person also has a picture of the main Steven Universe characters; one of Pearl by herself, because they identify with her the most; and a botanica-style candle with RuPaul on it. (They hasten to add that they're not worshipping the real person RuPaul, but the idea of "Mama Ru as the great benefactor.") They do seem to have a ritual knife (athame) and wand on the altar, but as they also add a set of prayer beads that they made themselves in Buddhist style, sort of, with four great sins represented that they just kind of personally made up, I'm just going to go ahead and say that this is not a Wicca that most Wiccans would recognize as such even before you get to the hexing part. I don't even know what to do with the fact that their ancestor altar includes Leelah Alcorn and a picture of Santa Muerte, whom they have decided is secretly a male in "a fabulous dress," and thus "the drag queen of the underworld." (Not everyone on your "ancestor altar" has to literally be your lineal ancestor. I could make one of these and add my cousin, who was almost my exact age but has already gone off to wherever one goes. I'm just saying, that's almost even worse than naming yourself after Gwen Araujo and not knowing how to say "Araujo," if only because we expect more of people who aren't Phil.)
tl;dr Has taken a tradition and bent it out of all recognizable shape anyway. Why don't they just join Feri? It's way better than Wicca if the gender binary harshes your mellow.
