The bottom falls out of the credibility of one critic 4 lines in from the start. So let’s look at the evidence.

Zunger read the manifesto, this guy did not.

So on the topic of manifesto contents, this guy has zero credibility or knowledge. Can’t even explain why Zunger’s position, which he sees as hostile, is not justified.

They see that they can scoop up a lot of naive support that way. However true that may be.
