Not agreeing who should pay the taxes or how we should distribute stuff is fine. I might get a little loud, but I see your point.

Not agreeing how centralized this or that system of coordination made for everyone's benefit should be is another one i might get loud about, but I won't cheer your death.

Not agreeing about whether we should emphasize rail water or electrical infrastructure updates first–as long as you agree we need all three, I'm barely gonna argue.

If you have some radically different vision from mine about what participation in and authorship of society looks like, I might think it's disgusting–but I probably at least want to hear it, you delusional freak.

Not agreeing on who is and isnt a person, who gets bodily autonomy, who gets to participate in society at all, and who dies in the camps–that's fighting words, and your death is cause for celebration.
