I continue to find people who are using feminine/masculine and woman/man interchangably, like feminine-aligned vs. female-aligned, when the two are very different things. You can be one and not the other- there are feminine-aligned men, masculine-aligned women, man-aligned feminine nbis, and woman-aligned masculine nbis. Proxvir and juxera are good examples of how this does not work. They are feminine/masculine aligned but are not woman/man aligned at all. The same goes for all other woman-related and man-related genders in a lot of instances.
It goes beyond that, too. It can also harm binary trans and cis people. There are lesbians who call themselves transmasculine and are going on testosterone, but because being masculine is seen as being A Man so often, people think they're someone using the term incorrectly when they're not. Trans man and transmasc aren't the same terms but for some reason things like this are shoved together despite a lot of these terms being made exactly because of this issue to begin with!
I guess as a nonbinary person it just continuously frustrated me to no end that people use the terms to mean the same thing when they're not. It makes talking about nonbinary expression and identity really difficult. Even in nonbinary spaces everything feels so binary to the point where masculinity and femininity are conflated with being man/woman-aligned. I dunno, I guess it's just kinda frustrating.
