There will no doubt be more than you think - if there isn't a neuro divergent society at your uni, you could start one?
At the very least there's loads of neurodivergent communities on lemmy to get involved with.
!autism@lemmy.world for starts
Also worth checking out communities for ADHD and neurodivergence generally - there's a lot of overlap to find stuff within.
They won't. The police exist to protect the interests of the state, so as long as the state doesn't give a shit and continues to pay sufficient renumeration to those willing to exercise unjust power over their fellows then... yeah.
