How can you deny the reality of transracialism?
Two men in Malaysia, one Chinese, one Malay were switched at birth, hence assigned Malay at birth in the case of the Chinese man, and Chinese at birth in the case of the Malay man:

And race in Malaysia is every bit as important than sex, Malays are legally Muslim (all of them, 100%, forever, unrenouncably), they are subject to positive discrimination policies, etc.
While the assigned-Malay-at-birth man wanted to renounce his transMalay identity and return to his biological Chinese status, the assigned-Chinese-at-birth man was happy to become trans-Chinese - he had a Chinese name, spoke Chinese, passed as Chinese, married a Chinese woman, ate pork, practised Buddhism.
I think you have to be PRETTY drunk at trans kool-aid to believe that a man, with different genetics, reproductive structures, body shape, facial appearance, can become a woman, but that a person cannot change race.
Race is essentially a description of a human grouping with shared culture. While this is linked to certain genetics, these genetics are not concrete in the way that XX vs XY is - outsiders can mix into the group and very quickly become apart of it. Certain races may have people of quite different appearance, reflecting different geographical origins of different parts of the tribe, but this does not negate their identity.
And don't forget that many supposed 'races' are in fact distinguished from each other based on RELIGION. While religion is largely inherited, these religious divides often reflect a past split in a single homogenous race based on war or whatever.
Now if what you are saying is that is offensive for a rich white person to go off and fly to Uganda and claim to suddenly be Bahororo, well then how the bloody hell do you justify rich white men claiming to be women?
There are plenty of British people who feel 'dysphoria' when they go and live in a country where the weather isn't shit, the food is delicious, the beaches beautiful, and people live more relaxed, less pressurised lives.
