speaking as a trans woman — for that matter, speaking as a trans woman, with a dick, who likes her dick, who enjoys and writes fantasies of trans women loving and fucking with their dicks — this is absolutely and unequivocally a bunk argument. to even suggest this is transmisogyny. a woman having sex with a woman isn't "straight", and if you say that a woman with a dick is a "stand-in" for a cis man, you are a transmisogynist at best. like, seriously, that's some TERF shit. it makes my skin crawl!!
is the implication that it would somehow be less problematic if glip exclusively drew cis girls? or that they should replace all the trans girls with cis men? if you're actually at the point of telling someone "your art would be better if it were less trans," how are you anything but a transphobe?
i do the exact same things glip does, by the way. my porn is totally filled with trans girl dick. because i love trans girls, and i love the possibilities opened up by having a wonderful and under-represented diversity of body types in my porn. reading distasteful arguments like this, i can't help but feel like i'm having my own toes stepped on. because that's what you do when you make this kind of bad faith attack — it contributes to an oppressive atmosphere that makes it more difficult for minority artists to make honest art. you might think you're "helping" — though i'm more inclined to believe you just kinda have a weird personal vendetta — but I can guarantee that almost every single artist you DO like is terrified of people who behave the way you do.
sincerely, a trans woman!!
