I’m still the same metalhead as ever, hah. Transition doesn’t change your interests, passions, and hobbies. If transfems are into some traditionally masc things as a product of being raised as boys, that’ll tend to stick around after transitioning. That doesn’t make them not women, but it does make them more likely to be in traditionally masc spaces than cis women.

And ultimately, I feel that’s a good thing - there’s really no reason women wouldn’t be interested in metal outside of cultural norms, and if more trans women are in those spaces I hope it makes cis women more comfortable to explore those interests too.
