I believe that no-one has the right to strangle a person - regardless of whether bare hands are used. There may be cases where the death penalty is right - I don't really approve of it ever but that kind of casual violence is unacceptable.
So, you would not approve of a rape victim attempting to strangle her rapist, in self-defense?
If there is a dispute, I believe that any violence should follow a trial before a jury of your peers. The rules should be made by a body elected by your peers. The enforcement should be by an institution created by your peers. These 3 institutions should be separate. In other words, democracy with all its checks and balances.
And I seek to add one more check: Market competition. Those three institutions are
not separate, and
cannot be while they all get paid from the same pool of stolen funds, and report to the same hierarchy.
In order for those institutions to be separate, they must be paid for voluntarily by individuals, instead of taking their funds by force, and
actually be separate, instead of part of a cartel enforced by violence.
