As a major supporter of any kind of "heterodox" or "revisionist" publishing/journals/etc. I forgot to put this in the argument with Assi back before he was killed by Jair Bosonaro supporters. It's that Quillette is exactly the Peterson, Brooks, Sullivan, etc. type of "edgy" "heterodox" writing that well, Sullivan himself is infamous for promoting at a prior job.
Where, it's not. It's new writers rehashing the same old tropes. Look at the list Pinker gives "heritability, sex and sex differences, race, culture, Islam, free speech and violence." They're producing exactly what Sullivan's New Republic was lamented for ultimately, an upper class salon for views ever so slightly out of the mainstream but definitely out of the academic mainstream that never want to grapple with conclusions and instead just continue "asking questions." While handwaiving a lot of the critiques by saying "oh, I'm on the left economically" or "I support LGBT" or whatever. That ultimately stops any actual exploration of a heterodox that goes beyond their own special circle.
Maybe it'll change now it's become popular and apparently is being well funded. But I wonder if that will make it more willing to let in more heterodox views even if to challenge them, or if it'll close it up to that squalid list of tropes.
