One thing I've noticed about the women Russ lusts after is that they're always heavily made-up, often surgically altered bimbos with faces like agricultural machinery. He doesn't like pretty women, girl-next-door women, glamorous women or even particularly beautiful women - he likes exhibitionist women. He just likes women who like to pose and like to get their fake tits out. Maybe in Russ' brain exhibitionist = available? He also likes women who don't seem to have strong personalities, or at least ones who come across as genuine or accessible. He likes Instagram hoes, not e-girls for instance, because e-girls talk a lot. Pop stars are generally less publicly talkative than say, rock stars - he likes Taylor Swift and Ariana Grande, but not Christina Scabbia or Alyssa White-Gluz. It's really clear that he just wants a sex doll with a pulse, and he finds women less attractive when they open their mouths - which is kinda ironic when you think of it.
Maybe I just have weird taste in women, but almost none of the thots he harasses are attractive at all.
