What you call "inventing", I call "having been unfortunately aware of his boil-on-the-public-discourse's-rear-end existence for most of his career." And to be very clear, he's not a crypto-Nazi. He carries water for crypto-Nazis because they pay his checks. Being Jewish is immaterial; this was the argument used about the gay, Jewish Milo Yiannpoulos not possibly being a literal fascist. Play that one back, too, and see where you get.
There is a strain of thought among the terminally gray-fallacious that somebody has to say "I am a trans-hating asshat" (which is different from being a Nazi, crypto- or otherwise) to be understood as a trans-hating asshat. He does it intentionally, he does it with malice, he does it to appease his similarly trans-hating-asshat bosses and customers, and we have the receipts. Res ipsa loquitur.
