Wars begin when two or more groups can no longer agree on the basics of human interaction. When one group decides the other cannot labor and earn a living anymore, nor be left alone to live in peace you are in a state of war. Lots of people threaten, bluster and talk, but the fact remains that when someone acts in a fashion that amounts to holding you down and forcibly injecting you, whether they physically do it or do so by forcing you to be fired and thus rendered penniless that is an act of violence, it is a felony assault and when done on a mass basis it is a declaration of war.
That act is no different than the Holodomor, a man-made famine, or the Holocaust which started with branding people who were claimed to be "inferior" or "defective" and sorting them out -- to be forcibly experimented on.
Through history mankind has made this mistake many times. The nature of war is that once it begins it continues until one side or the other sues for peace. The losing side sues for peace because the price of killing the next person on the other side becomes unacceptably high.
You don't win a war by dying for your side, in short. You win by making the price of your death so high that the other side is unwilling to pay it, and until one side or the other finds themselves in that position, or runs out of humans that remain alive the war continues. When the latter occurs we call it a genocide, because it is.
Whether the delineation to define the "enemy" is genetic, a ruse based on wanting someone's land and resources or based on a personal set of beliefs (after all, religion is voluntary, as are political positions) -- such as whether you're willing to undergo a medical procedure -- makes no difference.
