He's referring to the obvious hypocrisy in your political posture: saying that we need solidarity and empathy while egregiously misrepresenting and scapegoating persons who are very marginally different in terms of political philosophy and who are completely willing to discuss their political beliefs in good faith and saying
they are contemptuous of their fellow man. Also, you saying that JVS has great contempt for the working class is not only absurd: it's slanderous and despicable.

@Jack V Savage, you are wrong about liberals/Democrats consistently fighting for organized labor in a way remotely similar to the socialist left, to which xcvbn likely believes himself to belong. If that was the case, it would never have been blown to shreds. In fact, here's a WashPo article from last week detailing how Virginia Democrats enacted right-to-work and, now that they have both a strong legislative majority and control of the executive, are the only thing in the way of its repeal:
