without getting into my thoughts on this/your feelings, these types of hobby groups are closed loops and generally a sort of side quest in life.

Join a random volunteering event thru a local hospital, Veteran's affairs, shelter, hiking trails etc. You will organically meet people from outside your social strata/norms who you will organically hear from/reach out to and discover their organic hobbies/interest and gain a network. Why volunteer? It's free, quick, rewarding, and generally weeds out weirdos.
