Shapiro isn't a "pseudo-intellectual" and he condemned Dinesh's dumb comments. Ben didn't try and discredit the students, he called them what they are - teenagers dealing with trauma.
That is a very charitable reading of Shapiro, especially when he trots out as truth something like this:
"The whole reason that young people are generally less capable of strong decision-making is that the emotional centers of the brain are overdeveloped in comparison with the rational centers of the brain." (hint: this isn't remotely established and the study he is basing his claims on used ages from 10-18 and a sample size under 20 who were looking at facial expressions, and besides he is simplifying a complex issue for political purposes).
Or this:
"What, pray tell, did these students do to earn their claim to expertise?" (hint: no teen is claiming expertise on this issue, they are claiming that something needs to be done--you don't need to be an expert on guns to have an opinion on whether or not you should be murdered in school).
Or this:
"The answer seems to be relatively simple: Children and teenagers are not fully rational actors. They’re not capable of exercising supreme responsibilities. And we shouldn’t be treating innocence as a political asset used to push the agenda of more sophisticated players." (hint: none of this "clever" rhetoric remotely matters, because at issue is gun control and this issue is independent of whether emotional teens, sensible adults, or unyielding NRA-funded Republicans are discussing it. Shapiro--far from being an original thinker--is just usings lawyerly words to toe the party line).
I could go on and on... But to give him the benefit of the doubt: Shapiro is having a bad day meeting a by-line and vomitted out some trash in the NR. Or he is consistently off the mark, because he is not an original thinker.
And yes, his whole piece is an attempt to discredit the students. That much is obvious.
