People tend to forget that queer is a word that means weird, and if you step out of heteronormativity you're weird in the eyes of the heteonormative society, wether you want different relationships or no relationships at all.
The core wound of this demographic is being rejected and being relentlessly asked to stop your bullshit relative to romance and sex, and to get back in the ranks. The aroace definitely qualify.
And since being rejected is obviously a veeeeery common trauma in the queer community, and people tend to reenact unhealed patterns, it's not rare to see queer people rejecting other queer people with shit like biphobia, being picky with who "qualify" as trans, dismissing aroaces etc...
Let's put rejection somewhere on a dusty shelf for a while and see how it feels. I'm sure it's freeing.
