^^I couldn't take the thought guide nebbish in that link, below, one one can find a link that contains all the information without somebody to "help" with what to think. (recommend not opening the above video, vacuous commentator alert)
He's no more stupid that most of us. He's also right in that he's not in opposition to Sanders, just the fringe of Sanders supporters who think that mainstream Democrats are the same as Republicans. Like that thought guide guy who mashed up maybe 1 minute of Reich's contribution on Stephanopoulus's round table discussion into that 6 minute thought guided propaganda shit show you posted.
I can't find a link that doesn't contain an ad so apologies in advance.
Here is the real segment that your u-tube comedian used in his propaganda piece.

Note that the comedian's piece contained was no mention of alternative viewpoints expressed during the round table. Probably because Reich was treated civilly but in a patronizing way. Kind of like editing out the boos in a video about a Trump rally. Guarantee you and peckerbater will hate some of the some other analysts, right and moderate left.
Reich came across as a dysfunctional old man in this segment. Extracting him from counter-arguments to make him look presentable is one trick a propagandist would use. Just saying that resorting to this kind of crap shows weakness in the argument of this faction of the left. The tactic is called cherry picking.
The panel discussion highlights that other people don't perceive the Sanders left the same way you do. If you can stomach watching the segment, you might see that the arguments you and peckerbater go on about are seen as foolish and silly. If Reich is any example, this "movement" needs to learn how to present it's arguments better,.
