Meeting people is the easy part. Do this at:
Work Hobbies and Organised Activities Church or other Spiritual Communities Online, both locally and long-distance.
Though after meeting people, phase two is the most difficult: actually convincing people to hang out and do stuff.
Then phase three is actually creating and maintaining the friendship, lol.
These all become exponentially harder if you need complete ideological purity from your friends and romantic partners.
Warning: FAFO is not a good way to learn about hydrofluoric acid.
