Oscar Wilde has indeed been rehabilitated, though after his death. Admiring him is perfectly respecatble, as is admiring Henry V and other paedophiles. Wilde was accused of plenty of sex with underage boys(though the technical charges brought may have been only with adults, I am not sure.). The English have always popped abroad for what was made illegal at home, and Joe Orton(to name one notorious example) is a regularly performed and not-particularly-vilified plawright, though a read of his immensely entertaining diaries reveals in total detail exactly what he got up to in Morocco.
   I am not saying these activities should be ignored, merely that they should be not be got out of proportion.
And yes, I have got children. And no, of course I woudnt have wanted them to have underage sex with Gary Glitter, or Oscae Wilde, or Joe Orton, or Jonathan King. But all those options, for example, are considerably less bad than their being murdered, or run over by a drunk driver, for example.
