Not that they deserved to die but that it was necessary for them to die in order to save socialism in Russia or China or Vietnam or Cuba, whichever. Socialism is their religion, although it may take variant forms.
Their logic has always escaped me. Killing their OWN people to save socialism. Well Lenin, Stalin, et al, were known to have disdain for the Russian people. I tell LWers about their whole culture of death, and they just laugh. Actually they agree. When I tell them that their tactics are FASCIST, they go BALLISTIC. I always felt that not so deep down, they Left admires Stalin not for his Socialism, but for his barbarism. Deep down they WISH they could be Hitler, and put their own AMERICANS in gas ovens. They would love to take our 2nd Amendments rights away from us, not to make us safer, but to SLAUGHTER is. If you prod them, they will admit THAT, too. They fell that THEY should have guns... but not the rest of us.
