dude the reason people don't support the headcanon of Wiccan being trans is because it's just not realistic for Earth-616.
The guy is the reincarnated soul of the son of the Scarlet Witch and Vision. He’s dating the son of the most famed Kree Warrior and the heir to the Skrull throne who is seen as basically their Messiah. He can warp reality and create dimensions, he is literally a Demiurge which by definition is a being responsible for the creation of the universe. But please, tell me more about how a headcanon that he could be trans is the most unrealistic thing that his character could be.
