Middling liberals who says stuff like "I'm against both the fascists and the anti-fascists, I condemn all violence", absolutely will believe in violence when it comes time to defend their property rights, which they see as more important than defending the lives of minorites.
Most ideologies distinguish defensive vs. initiatory violence, which is what theories of property rights are about delineating. What is the analogous scenario in which someone is aggressing against "the lives of minorities" but liberals condemn defensive force?
