Since I'll never know what it's like to be a transgender person, I try not to make assumptions (one way or the other) about trans experiences -- aside from acknowledging the systemic and social barriers they face that are obvious.
What bothers me is that there seems to be an attempted normalization of "omnisexism" -- the belief that every person should somehow be open to consider a potential romantic relationship with anybody of any gender identity. Yet, this only seems to be fodder for judgment along a cisgender/transgender binary. Nobody, after all, is seriously telling cisgender lesbians to consider romance with cisgender straight men. Or telling cisgender straight men to consider romance with cisgender gay men. Or telling cisgender gay men to consider romance with cisgender straight women. Or telling cisgender straight women to consider romance with cisgender lesbians. Why is that?
To me, it feels like a toxic inversion of the "bedroom-policing" that most of us would EXPECT from people on the Far Right. So it's deeply troubling that some on the Left would try to do essentially the same thing from the opposite direction.
