I'm afraid that's just plain wrong.It's more to do with the fact that for centuries, we weren't able to be proud of who we are and now (in some countries) we are able to be so without fear of persecution. Straight (white) people have never had to feel that way.
Throughout history (and still today) millions of straight, white people have faced persecution, all around the world, for a whole host of reasons. Of course their sexuality was probably unrelated to the cause of their persecution. And indeed being white may render you less affected to certain types of discrimination.
But one thing we're good at as a species is discriminating against and persecuting each other for the most trivial of reasons. Sexuality is just one of those criteria. Disabled straight white people are discriminated against, as are a host of other straight, white people.
I really wish we could get away from the rhetoric that if you're a "cis white male" you can't have had anything bad happen to you (and you must have some super privilege to boot). It's a toxic narrative that seems to be more and more readily accepted.
