SuperStraight cannot possibly be a sexual orientation because its sole focus is genitals rather than people. People are attracted to people, not genitals.

The accusation that our only problem with trans people is their genitals is such a huge fucking strawman. We are not attracted to them as people, regardless of their genitals, because their biological sex is not compatible with our sexual orientation.

This is also some major heterosexual and homosexual erasure, suggesting that caring about your partner's genitals is somehow invalid.

Also, trans people are largely unattractive because they're hugely regressive basket cases with massive personal identity complexes and other mental illnesses they refuse to get therapy for and cover up with stupid made up identities. It sure as fuck isn't just the genitals.

and attempting to force a division in the LGBT movement that does not exist

What utter horseshit they're pushing. Sexual orientations are not "muh pronouns" bullshit. Tolerating the presence of trans advocacy in the LGB movement has been the literal death of the LGB movement. We want you idiots the fuck out.
