Reasonable people don't defend violence in either case.
You are you defending violence with whataboutism. And advocating for Machiavellianism.
Gross.

Either way, reasonable people who don't defend violence in either case are irrelevant, because things happen through violence regardless. What are you going to do about it when a horde of BLM rioters comes for your business and burns it down? Have a peaceful conversation with them about how much you don't think violence will solve the problem? No, you either have a gun or you don't.
The point of your argument is that violence is inevitable and therefore good?
