I'd say (and this is painful for many) that it really depends on who you are and how you act - if you're outgoing, or force yourself to pretend to be, and you talk, and you listen, and you don't immediately judge people (by whatever metric you come up with) - you can build community anywhere

Is it easier if you're in a group of tightly-knit people all nearly identical to you? Sure! But it's possible with work anywhere that has any population at all.

Social media and the Internet have let us self-select for "friends" who are as close to us as possible, there's ease because of the lack of friction, but that same lack of friction prevents our rough edges from being sanded off.

The number of people who could list what they want in a community, and when presented with a community that matches their list, cry that it votes wrong is way too high, just as an example.
