These numbskulls scream "Democracy, democracy" but will not engage in one of the cornerstones of democracy, debate.
They are fascists that censure, use private companies "misinformation" labels to enforce one party rule and shut down the free and open exchange of ideas and opinions.
I have the impression leftists will no longer come on conservative opinion shows for the reason most of their positions have become increasingly indefensible. The host becomes self conscious that they may be seen as bullying.
On the other hand I would be very surprised to see a competent articulate conservative invited on a left wing opinion show, like the Morning Joe. Like a lawyer asking a question in open court when he has no idea what the answer will be.
