Why do we make excuses?
For paedophiles/rapists when they are artists/celebrities? In any other instance an attempt to excuse an adult's rape of a 13-year-old with reference to her lifestyle and sexual experience would be universally, and quote rightly, condemned. So why are 'if's and 'buts' offered for the rapist in this instance?
Non-consensual sex is a strict liability offence. You can't defend such an offence with reference to the victim's own behaviour. In the case of an adult a court may, in some instances, consider an alleged victim's sexual history relevant in determining whether the rape in question has been fabricated/the sex was in fact consensual, but since a 13-year-old can never give consent the child's history/own behaviour is entirely irrelevant here.
