How is it undermining that and not affirming? I mean to fetishise a group is wrong, I get that and that is also my opinion but if they want to fuck a transwoman they want that because she is a woman which affirms the womanhood?
And the point is how is it transhate if you like the trans aspect specifically. Doesn’t make sense to me.
It is not a wordplay it is what those words mean. Phobic means something like hate or fear and phile means something like love or attraction.
