Well, if you're going to be pedantic:
There's a fundamental distinction, which you're missing, between initiated force and defensive force.
When someone robs or murders, that's initiated force. When the police use force to stop a robber or murderer, that's defensive force.
A "call to violence" is only applicable to initiated force.
For example, if I say, "let's murder Bob," that's a call to violence. If I say, "The police should arrest the murderer of Bob," that's not a call to violence.
Calling for a NATO no-fly zone is calling for defensive force, not initiated force, and thus is not a "call to violence."
I hope you can see how unjust and absurd it would be to call the defense of innocents a "call to violence."
