@Tony Xu My point is that Chinese or Russian style of socialism is out of bound for western politics. But Fabian style of socialism, which includes Bernie Sanders, is well within western political tradition. The UK labor party is direct descendant of the Fabian Society. The left of center parties of Western Europe, Northern Europe countries, such as the social democrat parties, are integral part of the democratic tradition.
I don't like single payer system. But it is well within western political tradition. For God sake, Canada and most Western European countries have single payer system. It is definitely not Chinese style socialism.
