i've seen this in other posts but it bears repeating:
if you are able to hire, house, or in any other way aid a member of the community - do so.
even a place to meet weekly and just talk about things will do wonders for everybody.
as things progress there will be fewer and fewer places that are hospitable to them and with that the mental toll of being an "outsider" will severely hurt them - not to mention the physical toll of being cast out.
the end result is the breakup of community and the loss of morale.
the fediverse (i think) already does a good job of mutual aid, however, it won't be enough.
