The Lemmy Compass
(burggit.moe)
I tried making a compass to represent some of the instances. Didn't know of any that I think would qualify as auth-right (strictly enforces rightist values).
I would probably give exploding-heads the authright quad tbh, one of their big communities for right talking points is called "parental rights" which is a pretty authright angle.
I thought about putting them there, but they don't restrict people to making right only topics. It's just that the crazies are more inclined to join that kind of place.
