There seems to be a prevalent misunderstanding here, in that most think that liberals are afraid of guns or want them all banned. I live in Seattle, and although I once affiliated with the left, I'm now pretty much a centrist. I still have many liberal friends who have a **** ton of guns. We go shooting alot. Liberals are not unfamiliar with firearms.
As far as a civil war goes, the liberals I know, are far more concerned with a zombie apocalypse or the big bad police state trying to come take their guns. No one talks about shooting up Trump voters
