There's been so much progress on things related to sex like our understanding of consent, and yet conversations like these throw a wrench into all of them. There is a clear contradiction in tieing social progress to who you're willing to take to bed. The latter is nobody's business and consent can be refused (and rescinded) for ANY reason. It doesn't matter if it's height-related, weight-related, or even race-related. They're all valid reasons because attraction is complicated.
Genitalia is also obviously a very big valid reason, but I hate how it always starts a looping conversation of "I hate penises!" and "yeah, but what if they're post-op!? If you don't have sex with them then, you're a bigot!". It completely downplays attraction being a mental thing as much as a physical thing. Yes, people can ALSO be turned off sexually from someone at one point in their life having a penis, even if they no longer have it, and that's just as valid. You can even be a major trans ally, going to protests on bathroom and military issues, and feel this way. You can wants rights for and be friends with people and even entire groups that you don't want to fuck.
And what sucks is there's a segment of the terminally online populace fooling people into thinking their extreme mindset is widespread. It's how shit like Super Straight or that BBC article can take off, when in reality few non-terminally online trans people will make you feel bad about who you're willing to have sex with. They understand how complicated attraction is, both the physical and the mental side.
