Gender and race are social constructs. Sex and ethnic ancestry are science.
Transracial or transsexual people want to shift between gender/race boxes, because they do not feel socially, spiritually, mentally fit/compatible with the social constructs (race, gender) that traditionally align to their scientific facts (sex, ethnic ancestry).
This is a symptom of a society that chains people into social boxes because sex/ethnic ancestry.
If we as a society want to move to place where social constructs lose relevance, we cannot support and perpetuate the existence of these social constructs by acknowledging that you can actually shift between them.
Therefore if you consequently want to get rid of social stereotypes, celebrating transsexuality/transraciality is counterproductive.
