I agree with the other commenters but also want to add that I think it's this bizarre childishness from young adults where all sex is icky but they still want their oppressed minority card punched. They can "be gay, do crimes" without actually being homosexual, so long as they are still "romantically attracted" a gender they found on tumblr. All they have to do is combine enough buzzwords on the internet and poof they are now gayylmao and can jerk off with the rest of their fellow queers in the discord server whenever someone starts the "we're soooo gay teehee" posts. In reality, they're a run of the mill young adult who's "partner" is online or little more than a roommate.

I also think it's virtue signaling culture taken to its extreme. I didn't start seeing this separation pushed so hard until the Q and A were welded onto the LGB(T) and I think it's because in their circles, forgetting a letter is an unforgivable sin. It's so ingrained to constantly include the devils advocate ("nOt EvErY oNe ExPeRiAnCes SeXuAl AtTraCtiON!!!1""WhAt aBoUt NoNbInArieS???????????????!!) that its easier to redefine and separate the types of attraction so that all 7.8 billion humans on the planet can be Queer™️ too.
