So what is his issue with the "extreme left" exactly if those were the shows he picked?
You could legit just read the screenshot and answer your own question.
Looks like Jerry is a pretty mainstream liberal who is okay with shows tackling issues of their own volition, but doesn't appreciate the current production model of everything having to pass through focus groups, committees, and wanker consultants, coming out the other side so impotent and safe that it doesn't arouse the intellect enough to really make a point or stand for anything specific.
Like if you watch Disney stuff and think that's normal, you're part of the problem.
