What kind of unholy train wreck happened here while I slept?
I mean, if you ask me I love queer as an umbrella term but due to its history as a reclaimed/under reclamation slur, some people, particularly the older generations are uncomfortable with it, which I can respect. "Gender and sexual diversity" or "Gender and sexual minorities", though I think I'd prefer "Gender and Attraction diversity", though most forms of attraction are sexuality-adjacent enough that GASM works. But all of them are flawed.
. "Anti-leviticus defence league" is a nice find, El Mac. XD
What there isn't much work being done (except by the usual respectability politic suspects) on is rejecting parts of those minorities because "If there's too many of them then it's too hard for other folk to understand". The need of each group to fight for recognition and acceptance is not contingent on the number of groups the common people can manage, and leaving the smaller groups to fend for themselves, while it may make tactical sense for the larger group, pretty much amounts to condemning the smaller group and their needs and rights to be completely forgotten. Not an acceptable reasonable outcome unless there is something fundamentally unethical (ie, attraction to those who cannot consent, such as, for example, children) about that particular minority.
--------------------
Polyamory is a relationship structure model (regardless of attraction), so completely different from aromanticism (which is purely a question of attraction, not of how you structure your relationship). Not to say it doesn't have its place in the movement, that's a whole other teakettle, but simply that regardless of whether or not they do, there is no meaningful link between polyamory and aromanticism.
