Calling him "small minded and uninformed" is an example of what he's talking about.
You are unable to address his actual points and truths, so you resort to insults that offer nothing to anyone.
You are not successfully presenting an alternate point of view, which is exactly what he is saying is going on with this generation that struggles to engage in a reasonable way.
Everything he says is either so plainly obvious that it is a trivial banality or a distorted strawman of various types of people and beliefs he has a general animus towards. To me, it sounds like a vacuous whine, and there's not really much of substance there to engage. Cheers.
