Nah they're just racist. The thing is a white liberal can become a homosexual should they choose to have sex with someone of the same sex. They can even theoretically become trans.
No matter what a white man or woman does or how they feel about attraction or their gender.... He or she will never be brown. Sorry I'm not putting up with this intersectionality shit.
Sure. But if I, a straight man, slept with a man, then I would become a homosexual by definition. Or if I pursued becoming trans. Now it's unlikely I'd do this but theoretically it is part of the set of possible actions..
There is no action a white man or woman can take, not surgery they can pursue, that will make them brown.
