Blackface was and is used to mock and dehumanize black people. Drag was and is used to play with and mock gender roles, most commonly by gay people of both sexes to bring people together, not to dehumanize people. I get some people don't like it, but really I don't see 'women' as the focus of most drag queen acts, I see hyperfemininity. I very much do not see those as the same.
Yes, some drag queens mock women and some drag kings mock men, some are incredibly sexist and I get despising individuals or how the commercialization of it does seem to hinge on that aspect over good characters and play which has turned me away from some of it, and I can certainly see the issues others have raised when random guys do it to embarrass each other, but that doesn't erase the history and the value drag shows have had for some of us and I do not think it's comparable to blackface or redface or yellowface. Race isn't the same as gender roles. There is nothing within race that is a seperate characteristic. We should all be able to laugh at gender roles, even more when taken to an absurd but logical extreme, and use it to discuss them.
I find it kinda odd, actually, how both certain groups of TRAs and certain groups of feminists seem to have it out for drag. Would it really be better if we didn't publically play with those roles? Must we take gender very seriously now and never use those roles or discuss them in a way that others might find funny? A little sunshine and laughter can expose a lot.
There are plenty of women who use masculine stereotypes and dress for comedy and other forms of entertainment. It can be good fun and a good laugh. The last ones I saw were at events run by women's groups. Most drag shows are tiny amateur affairs so
I'm not surprised many haven't seen good drag at all let alone drag kings and really, I know it's not everyone's cup of tea. And really, if we're going to view it as part of patriarchy, drag kings have a far harder task as femininity is just a lot easier to make look ridiculous with how culturally restrictive, the pain in the ass maintanance of it, and just weird elements that are even easier to see how ridiculous they are on a guy who isn't expected to conform to them and drag kings are less likely to get mainstream as some drag queens have because it's women in a masculine role and, in my opinion, often looking way better while they play with hypermasculinity than many men do and make fun of traits viewed as masculine. I get why some men wouldn't want more women doing and enjoying that.
So yeah, I know I'm biased, I enjoy it, and I know some people are assholes about it and when doing it, but I think messing about and having a laugh at gender roles can be great fun and not inherently equivalent to blacking up.
