I've also noticed that people on the internet usually react to a woman's claim of assault or rape with skepticism and disbelief.
Even in this thread, there seems to be a lot of empathy for the alleged attacker -- whose story we haven't heard -- and far too little for the victim. We know what she says happened, we know it's been corroborated by two witnesses, and we know the resulting trauma it's caused her, so why are so many people feeling sorry him and not her?
Which more information would you need? There are two other people that corroborate her story, and Joe says he's not saying anything.
