yeah there's a weird divide in alphas. I used to know alot of alpha NTs but after school I think those that didn't end up with SFs kind of drift off into a world full of alpha NTs while us SFs drifted off into a world of alpha SFs. I'm surrounded by ESFjs and ISFps now in my circle of friends, but alpha NTs seem to live in a non-intersecting world IRL.
Also the alpha SFs tend to not even consider people from the alpha NT world as viable romantic relationships (I imagine it's the same for the NTs)
