What I am saying is if you involve yourself in violence (and directly profiting from violence) you should not be allowed to act shocked when that same violence turns up on your doorstep

Not ok, but anybody who is ok with terrorizing, say, an Iranian civilian nuclear scientist ought to be equally indifferent to this.

Pretty much everyone thinks that violence is ok against certain people. You probably do too. The disagreements are about who violence is ok to use against.
