It is perfectly reasonable to be able to use force to counter the initiation of force.
Using force is not always wrong. Initiating the use of force against others always is.
Ok, I think Libertarians and Conservatives can agree with that..... I think. LOL
I cannot think of any scenario where Initiating the use of force would be ok. well....other than punishment for non-force crimes, like a embezzler. The cops would initiate force to put him in jail, I am fine with that. I think that would qualify as ok for you also?
