I imagine Josh's Trad (tm) turn comes from him regretting a lot of the weird turns his life has taken, and thinking that in a more traditional society, he would've become a more normal person with a normal life. He's probably right - from what we know, his upbringing was pretty dysfunctional. But I also suspect he uses it as a crutch/excuse to keep being how he is ("I'm a product of a degenerate age so why try") rather than motivation to be better. I'd love for him to prove us all wrong, but I doubt it.
On the other hand the people arguing with him were definitely rustled too. If Jewsh's childish /pol/ rantings are enough to make you lash out in insecurity about your MGTOW hentai addict/cat lady lifestyle (likely practiced by many kiwis), maybe you should reexamine that.
