Why don't you ask someone who has been date raped about how it has affected them?
Actually there's evidence to suggest that date-rape is more diffcult to process than the kind of attack you are talking about becaused there is no memory of trauma to resolve and address.
But you carry on making sweeping assumptions. This "degrees of rape" makes me sick. It's all rape, all rapes affect people in different ways, all rapes are vile.
Is of course correct, but not to even acknowledge the vulnerability of a claim of rape in certain circumstances, when even a court of law might find it nearly impossible to know if consent was given.
