@Master EffeXHmm, I never thought about that before. I mean when I first learned about Xmen they seemed to be a menace and outcasts. But the Xmen came along to try to make peace to bring humans and mutants together. But of course, humans looked down on them like they were abominations. They didn't want anything to do with any of them. And then Magneto came along and looked down at humans like they were weak. He didn't care to be peaceful he wanted to take over. In one series I saw he wanted to make everyone mutants.
So it was different ways they saw mutants as superior and also "different". Some do actually want peace but others seem to abuse their power. Like you said showing what they can do and humans can't.
