"I just have no understanding why people think what he is saying is new or revolutionary, he is a bizarre mixture of New age mysticism and right of centre thinking. He also has an astounding lack of understanding of anyone whose life differs from his own."
They don't. You've fabricated this narrative. It's quite clear many of the posters hear have formed opinions based on shreds of information.
People do not think what he is saying is new. They know it is (some of it, at least) the truth. This era of leftist theory painting groups of people as those responsible for other group's demise/misfortunes is a narrative a lot of people simply do not buy in to, and up until now any other analysis of social constructs other than the left's remarkably self-assured, supposedly progressive version has been seen as an attack on "progress" (as defined by the left, that is). He has the nerve to actually question the infallible left, and people like that. The left, of course, fucking hate it.
He is not championing new thought, he never really claims that. He IS championing logical(ish) ideas and the responsibilities of the individual.
It is, and will become dangerous, to judge one by (one of) the (many) subset(s) they belong to. It is ironic, since it attempting to combat exactly that behaviour.
As for his interviewing persona, you have to be aware he's had dozens of lefties combat with him over the last two years (culminating in the remarkable Cathey Newman interview), it's hardly surprising he now walks into an interview with his guard up.
FWIW I would define myself as liberal, centre-leaning-left. However I'm becoming very sceptical of the leaning part lately.
