btw there's no hard barriers between any queer identities- where one identity ends and another begins, they meld together, creating a gradient between the two, and every other identity around it. it's one big gradient, not rigid boxes that can never be touched by one another. queerness involves embracing those gray areas, celebrating them, and the lives of people who occupy them. being unique does not involve casting away those who are similar to you- there are no barriers between different queers, we are all part of the the same beautiful tapestry.
"drag kings are boring, they just look like normal guys." this is not true for all drag kings, but it is only boring to you because you have failed to realize that manhood and masculinity also require constant over-performance around the clock, especially with strangers you don't even plan on getting to know.
these things look "normal and dull" to certain folks because they haven't had to live through what it's like to have to literally perform manhood for every single person you meet, because it's expected of you to be stoic, strong, and "manly," and a lot of that is reflected in clothing and personal grooming as well. our society has such a rigid view of manhood that there is basically no wiggle room for personal expression in interests and activities that are not traditionally "manly". men are told they are not men if they do not uphold these traits.
this is a performance.
gender is a performance no matter what you identify as. men and mascs have to over-perform manhood as well, just as women have to, trans or cis.
