You've never talked to a single socialist, anarchist, leftist, etc. about civilian firearm ownership before? It's very commonly thought of as a necessary evil to prevent systemic oppression. Maybe don't spend so much of your time talking to trumpers and neoconservatives?

To wit: there is no "right people" to want to shoot, and anyone who thinks there is probably has their own tribalism issue to work out. Community defense specifically does not have a target right up until the point someone else is an aggressor, and ends when violence is no longer needed. This is why you never saw "antifa burns down trump supporter's house" or whatever in the news.
