Note that communities doesn’t just refer to the hippie variety. Community is also: your family, your village, your online friends, your class. Community are the neighbours next door. When I moved into my new home my neighbours came and brought food - and I realized that I really didn’t know enough about communities anymore, so I’m here to learn.
A village community is different from an online community. You cannot just change it from one day to the next. Not every expectation in a village might agree with you: there is a soft pressure from some people to join some of the religious festivities and have the priest bless your house, not so much my thing - but it limits full integration and makes that I remain foreign.
I moved into the first community of the hippy/punk variety when I was 17, and even though it appeared a continuous failure at the time (all the conflict, all the people arriving and leaving) it did keep me alive and sheltered and in good spirits for 4 years and the place is still in the hands of a group, not one person, till today, yay.
