Easy. Democrats do not follow conservative media, at all. As far as Democrats know, conservative media promotes reinstating slavery.
You are so correct. People on the left do not see anything except what comes from the propaganda media. They live in a parallel universe from us. We are forced to see both sides because the leftist media is so predominant. They never see anything that contradicts the lies and the irresponsible slants of the lying media, one of whose greatest powers is the power to omit.
I suppose that could be true.
