Well you do have to consider what exactly was acceptable and unacceptable back then too. Firstly, men using their fame and celebrity to get women to have sex with them is something that is about as old as the concept of fame. So then transplant that onto a society where sex with underage girls is something that's considered a bit naughty, but nothing to worry too much about, where sexual harassment of all women is just a fact of life, and where there is no oversight of people in power, and it's not surprising to see abuses occurring. Someone like Jimmy Savile took it to extremes, of course, but I read an article just after Bowie died entitled "I lost my virginity to David Bowie" detailing how two girls aged 14 and 15 went up to his room, smoked marijuana, and had sex with him. It was almost bragging in tone about what was technically a sex crime. And he's not the only one. Read about the so-called "baby groupies" and you'll see the likes of Iggy Pop, Mick Jagger, Rod Stewart, Alice Cooper and Marc Bolan implicated in sex with underage girls as young as 11.
Where's this info regarding all the other "pop" stars? Never heard of any of them being implicated and I've read a lot about the paedophilic nature of Hollywood/music industries etc. It wouldn't surprise me which is pretty sad to think.
