Since this is a thread where I can post an unpopular or controversial opinion, I will say this:
I wish for an X-Men AU where mutants are NOT feared and hated and accepted by society. While I understand why mutants have been feared and hated over the last 50+ years, as they are considered a metaphor for people IRL who are considered different (POCs, LGBT, etc.), this storyline has been done to death. I'm interesting in seeing what the MU would be like if mutants weren't feared and hated on a daily basis.
