well, yes and no

to my personal experience, it can feel kind of transphobic, as being in the position of being rejected just because of your genitals, and not because of the rest of your personality and appearance/gender expression just feels wrong and mean somehow, but if I try to rationalize it, saying that such pereference is transphobic feels just as bad, as you cant force someones pereference

there needs to be said that the person did not see the implication of praising/complementing someones genitals that were the problem (in the case of the original post "And it would propably be difficult with me going 'I love your boobs' and they're always like 'I hate my boobs'"). As praising or giving a trans person a complement on the bodyparts which are a big part of their disphoria is just mean and very painfull for most of them (this was propably unintended tho, and I expect the original postter didn't think about this, but still)

[pre-anything transfem btw]

yes, I have at least trice at this point, twice of which starting with Voxus's reading videos (no /s)
