You seem extremely judgemental and narrow in your view of the world. This is probably why you have difficulty forming deep friendships without the social proof of family.
As a counter example, I've made some of the best friends of my life through walking my dog at the local dog park over the last decade. Seeing how people are dedicated to and treat their dogs gives me a great insight into their personalities.
