Wtf does that actually mean 'non binary identities are valid?’
It’s copied and pasted from Stonewall’s sloganeering campaign materials, isn’t it?
That whole “TWAW, TMAM, NBIAV” spiel reminds me of reciting a prayer.
I imagine that if you asked them “what do you mean by valid in this context” you’d get a lot of platitudes in response. And wouldn’t get a definition.
