Diversity is a good thing, but it should never be done at the expense of any group of people. In the last 10 years there have been countless examples of a white character being race-swapped into a person of color, but I can't think of a single example of a race-swap in the opposite direction or a race-swap between two non-white races. That clearly shows bias against white people.

Trans people are not an oppressed minority. Yes, they have mental health problems and a much higher suicide rate than the general population. But otherwise, they are some of the most privileged people in Western society. In situations where one transwoman wants to use the women's locker room and a dozen women feel uncomfortable, the desire of the transwoman wins out every time. That's privilege. I'm in favor of equal rights for everyone, but participating in sporting competitions against the opposite sex is not a human right. Making irreversible bodily changes while still a child is not a human right either.
