Great thread!
Awhile back we had a really engaging discussion that also explored some of the aspects of mutants and x-men as externalizations of identity and vehicles for self exploration, discovery and creation.

For me, being a fan of the X-Men has everything to do with my affinity for the 'mutant' outsider. It's a concept that is real for me and drew me to the comics way before I was consciously aware of that being a deciding difference between the X-Men and other mainstream comics.
& that much has stuck through the decades beyond the comics too.
"I am a mutant" is something that just hits very close to the marrow for me.
Even out of the comics context, the word itself resonates.
