I have my General license, but really just listen. Shyness and PERSEC tend to hold me back, but I do own up to the fact that I’m shooting myself in the foot by keeping quiet.
If things go down (and assuming another Carrington event/EMP hasn’t damaged stations) then I assume communication will happen even if not as organized as before.
One of the biggest issues in my area is the average HAM is quite elderly and, given their communications, quite a few seem to be in poor health.
As for the political/religious orientation of groups? I think humans are always going to be tribal in nature so finding your tribe is a really important aspect of prepping. You may have to encourage friends/family to become HAMs if you aren’t finding what you’re looking for within the pool of active operators.
