TheMarzipanDildo came closest to my views on this thread.
Contrary to those claiming there are big differences between GC feminism's take on how women are treated and their take on how race is treated, I see the GC analysis covers both areas clearly.
Namely, that GC feminists would argue that it is not 'gender appropriation' for men to wear long hair, make up, etc eg Boy George, the New Romantics, etc, while making crystal clear they are men and doing it respectfully of women. But drag is offensive because it is harmfully and negatively parodying women. Also, transwomen who put on women's clothing and claim they actually are magically transformed into women are offensive because they do not have women's biology and lived experience, including of oppression.
To apply that to cultural appropriation, people of any race who want to wear street style clothes or a kimono-style dressing gown because they like the look and think it looks good are not a problem, and calling that cultural appropriation is like homophobic, very traditional right-wing men who object to men wearing 'effeminate' clothes and think men should all look like men, and women should all wear make up and never trousers etc. ie 'stay in your lane'.
What is a problem is where people wear clothes or styles of other cultures to deliberately offensive parody them, eg blackface, much as drag is offensive because it offensively parodies women.
The third category, of white people pretending to actually be black in order to benefit from it in career terms, eg Rachel Dolazel or white models darkening their skin, is also offensive, in the same way that so-called transwomen claiming they are actually women and using that to get awards, jobs, rights etc that women have fought for, is offensive.
So I think a GC lens is perfect to explain issues of cultural appropriation, actually.
