Oh, really.

"Gay pride" was, I take it, the granddaddy of them all. It doesn't seem difficult to think of some successful gay people, but here in case you're having trouble is a very short list. Oscar Wilde, world-class playwright. Tim Cook, CEO of the world's most successful company. Jóhanna Sigurðardóttir, prime minister of Iceland. Benjamin Britten, greatest English composer since Purcell. Freddie Mercury, rock star. Alan Turing, mathematician, computer pioneer and helped win WW2.

"Black pride" is a thing, I guess. Martin Luther King, social and political reformer. Barack Obama, president of the world's only superpower. Desmond Tutu, archbishop. Toni Morrison, Nobel-winning writer. Neil deGrasse Tyson, astronomer and TV star. Louis Armstrong, jazz musician.

Those are actually the only two major "pride movements" I know of. There are "white pride" and "straight pride" movements, kinda, but they're quite different in character and I think in motivation, and in any case I don't imagine you'll have any difficulty thinking of successful white and straight people.

I expect there's such a thing as "trans pride", but transness is much rarer than gayness or blackness and was socially unacceptable for longer. (Hence: fewer of them, and more obstacles to their becoming successful.) Still, off the top of my head I'll name Wendy Carlos, musician, and Sophie Wilson, engineer, both of whom were world-famous (as men) for things that had nothing to do with gender identity before coming out as trans.

What pride movements were you thinking of that don't have examples of successful people to look at?
