It’s really quite simple - some people look at the world as it is and see injustices everywhere and want to blow up the status quo and replace with their untried untested wet dreams. Others look at the same world and try to make the best of it by learning and appreciating rules for living that have worked through millenia and gradually improve things as they can.
I believe that there is a genetic component to this difference. Specifically something in the genes that make some people highly uncomfortable with the sight of inequality. To them any lack of equality is injustice and the sight of that eats away at them.
The naive conceit that guns are inherently evil serves as an example that may fit within this conflict of visions. The unconstrained vision imagines a world without guns to be achievable, if not desirable, all the while ignoring the historic fact that tools of innumerable kinds have inflicted death and bloodshed and thus call for what we all should, and do, agree upon: provide for the common defense. Anyone who runs for public office while advocating the total abolition of guns is by definition self-disqualifying in terms of oath fidelity and should therefore not be allowed ballot access.
