Surely you are not. You are merely suggesting to use bullets or other forceful methods against people whose notions you dislike.
How else are you going to stop an invasion or a genocide?
I'm suggesting bullets and forceful methods to STOP their ACTIONS. Not because I don't like their notions; they're free to express any idiotic notion they want. But if they put those notions into action, then any method necessary is fair to stop them. Because you don't stand by while someone slaughter people and steal their homes for asinine reasons.
But once they start invading countries and shooting at people over their completely moronic notions...yeah, you can bet I'm going to argue for doing whatever we can to stop them.
So what's wrong with the sentiment that "Crimea is much more Russian than Ukrainian"? I dare say majority of Crimean inhabitants might share it. Are they crazy nationalists and must be dealt with bullets?
No.
The people who live in Crimea, decide Crimea's fate. That's what I said from the start and I still say it. Ukraine's right to Crimea exists only so long as the Crimeans accept it. Moscow has a right to Crimea if the Crimeans so desire it. And neither have a right to Crimea, if the Crimean would rather be independent. In all cases, there is nothing mad or insane, nothing deserving of being shot, about Crimeans chosing the fate of the land they live in.
As a general rule of thumb, the people with a right to any piece of land are the people who live there, or, in some rare cases, the people who were recently kicked out by force, threat of force, or other dishonest manners.
How you find out what the people want is a FREE (as in: not under military ocupation, Russia) and fair referendum. Until you have the results of such a referendum, you assume what the people want is the statu quo.
