I have no problem with men using violence to protect themselves.
In fact i have no problem with anybody in this whole wide world protecting themselves against those who initiate violence.

Believe it or not in the netherlands you would get extorted, kidnapped, gaged or killed if you have pepperspray if you don't submit to the initiators of violence.

edit; I read my initial reply and I see now that its not clear that I meant that initiatory violence needs to be stopped. You are correct defensive use of force/violence is always justified what else would otherwise stop the aggressor. Be it a tyrant, a violent spouse, a bully etc.
