That linked to post was a response to an existing ongoing discussion that brought transphobes out of the woodwork. That post also had transphobic replies, and there were multiple discussions going on at once with active transphobes.
It was the ongoing transphobia that occurred around the initial discussion that prompted my post, not any specific single post.
But you need to be aware, cis people talking about the reasons they are valid in not wanting to fuck trans people is something we see all day, every day. It's normalised for people to just volunteer how unfuckable they find us.
And whilst that discussion might have some valid spaces in which it can be talked about, a meme community on an instance run by two trans women is not that space
The original post was an image with the text "Hey you, straight dude: are you attracted to women or to femininity?"
I posted a response that said I like boobs & pussy, and then someone (who turned out to be ace, and just was curious) asked if I would date a trans man.
