I love the unintentional implication that Sulu (either Sulu) is none of those things
We (that's 'non-heterosexual' people) "deserve" the exact same things as everyone else. Hence, 'equality.' And I don't recall anyone screeching about "
creating unique etc etc'" characters whenever a
straight Trek character got their first on-screen love interest.
'Picard didn't have a love interest in the first season of the show. Why should they change him to having an interest in women now. They should have just created a brand new blah blah blah...'
This whole "don't change an old character, just introduce a new one" (not to mention "LGBT people 'getting' Sulu") reeks of the old fan chestnut "
I don't want other people playing with my toys!!!'" The writers control what/who the characters are, and they can do so via retcons. That's all there is to it. If you want that power, best start praying that a job at Paramount falls in your lap.
