You don't think the name "Spider-Woman" itself counts as evidence?
A) She's never actually called Spiderwoman in the movies as far as I recall.
B) If she is, she either chose that name herself y'know because she's a trans woman so obviously she would call herself a woman. Or people who just figured it was a fem person in the costume called her Spiderwoman because, y'know secret identities. Even transphobes would presumably call her spiderwoman because they wouldn't know whether or not she's trans.
C) If the writers, the ultimate arbiters of whether or not she is called "Spiderwoman", did want to make her trans then it is likely because they accept trans women as women.
So every possible scenario for who calls her Spiderwoman, inside and outside of the text, would mean that a trans woman would be identified as a woman.
So no. This is just a dumb transphobic take because you just wanted to get it out there that you're transphobic or trolling.
