I don't know of anyone who values diversity in gender/religion/sexuality/etc but draws the line there, and I know a lot of very unusual people from all walks of life. That would be a weird line to draw. A gay genderfluid punk rocker probably has lots of experiences a biromantic genderfluid cellist would be fascinated by.
Diversity is good. The more intersections, the better. Why do you think anyone would draw this line?
