I think I've had or developed this same paranoia complex myself (username extremely relevant), related to having conservative beliefs among liberal/regressive friends in a clique. Adding in the vitriol in ideological talks over the past several years, the complex has amounted to a full-fledged phobia of public confrontation.
And you may be correct that my past friendships never were as close as I thought, but perhaps not completely because of paranoia.

They're so deep into their persecution complex they can't [be] true [to] anyone enough to be friends.

I don't know if honesty was my problem, but general sociability certainly was (and is). I have always been quiet, and I did (do) not feel naturally inclined to talk about myself or ask others of themselves. I am extremely passive in that regard.
