If + covers and more why are we adding 2S also although the particular culture referenced is unique as they all are its not clear 2S actually references a different type of sexuality different from intersex and or bisexuality and the acronym was already unweildy as fuck.
There are so many different aspects to sexuality it seems silly to try to abbreviate. Also if you add enough letters you’ll eventually cover anyone not completely boring.
Meanwhile other folks are how adding 2S or just 2 to the back end. I vote for Q+
