I wouldn't judge a man by the presuppositions of his life, but only by the fruits of his life. And the fruits - the relevant fruits - are, I'd say, a sense of charity, a sense of proportion, a sense of justice.
I think I have one answer, that is partly religious and partly secular; and that is to say, we ought to at least recognize that we and the Russians are in a common predicament. That would be religious in the sense, "Judge not lest you be judged."
We judge the Russians because they're living under despotism and we don't like it, but we've gotten into a fix now where we're living in a common predicament, and we ought to recognize this common predicament.
