Don't get me wrong, but from a relationships perspective, your comment sounds more like a frustrated spoiled ex-girlfriend than a friend. I mean, friends don't go badmouthing their friends on the internet. It's a dick move.

Regarding "theories of everything" and stuff like that. Well, lots of people have those. If I were to call everyone that believes in god or horoscope lone losers, then the asshole would be me, wouldn't it? I know it's different, but also, it's not.

Friendship doesn't require that you buy into the other's vision in order to want them around. That's ideology. Perhaps you misunderstood what friendship means? It's ok, the world is in a weird place right now.
