Kahane was interviewed by Playboy Magazine at least once. In the 70s and 80s people actually read the articles and they invested in textual content.
I assume Hugh Hefner was a life long liberal but if you look at the way things are going these days, he should be considered as part of the Patriarchy and had Playboy still existed in a meaningful way today I would expect hairy butch lesbians with mullet and twiggy faggots would be picketing in front of the Playboy Mansion.
