Goldmund is a dude that gained some popularity online as a pickup artist, and he even wrote a book on seducing women through photography. Many people protested his book, though, and many women felt offended by the notion that men are printing manuals on how to lure potential mating partners back to their houses.
I honestly can’t say how offensive the book is (because I haven’t read it), but seeing his Twitter profile, I can say that it’s pretty repulsive. Well, he is currently getting a lot of attention, and it’s not good.
Someone asked him how to spot “a feminist out in the wild”, and Goldmund offered a list of “feminist tells”:
Even though it might be a pretty insulting way to describe women who don’t want to talk to sweaty men in coffee shops, many feminists actually found Goldmund’s list pretty funny, and they truly believe it’s accurate.
