Application of single attraction logic to split attraction people will not make your argument correct.
Cishets are not LGBT = a true statement.
Asexuals, aromantics, intersex people, and others who use the split attraction model who happen to be “cishet” are not simply cishet.
E.g. a cishet ace isn’t a cishet, they’re a cishet ace. Erasing the “ace” to make them sound the same as actual cishets doesn’t change the fact that…you erased their asexuality to make your logic work.
Actual cishets don’t have multiple orientations/identities. Claiming those with multiple orientations/identities that include cishet doesn’t magically make them identical to actual cishets, its simply an asshole’s tactic to make yourself appear to be correct through erasure and exploiting people’s lack of understanding of intersectionality.
Just because teenagers on tunglr dot com fall for your blatant washing away of identities to paint other marginalized people as their own oppressors doesn’t mean you are correct, clever, or in any way going to get away with it. You’re transparent bigots, and the community is not going to support you.
