"Aren't superpowers a form of magic?"
You would think! Batman and Superman both are famous for muttering "I hate magic," in the comics. It's one of those weird disconnects in comic world logic.
Like the world loves The Fantastic Four, but hates the X-Men. Because the Fantastic Four are normal humans that got their powers from space, and the X-Men were born with their powers therefore they can't be trusted.
Just shrug and move on.
