I'll take a stab at it: even though all the other alphabet people are present out of degeneracy, the asexuals are part of the group because they're not heterosexual, making them atypical, making them part of "the community".
In real terms, they added a "marginalized group" (whether people want to be associated with it or not) to grow their coalition of fringe minorities.
Them trying to claim asexuality is peak clown world. Why would an asexual want anything to do with these degenerates?
