I don't know if it's a new trend or something, but lots of people have something interesting to say, and say lots of hogwash besides and everyone gobbles it all up including the hogwash. You don't have to go all in when reading someone's work. For example, I read Freud and it was quite interesting. Most of it was horseshit (although historically interesting), but he still made the point that we don't do all that we do consciously , which was hugely important.

Ideas and memes (in the original sense) are there to be examined and weighed against one another, not followed blindly.

So Petersen (I'm not really sure who that is), why not, he might have some salient points, even though he seems to be a controversial figure, apparently rightly so.
