First, I made a mistake: 1 in 6 women will be victims of sexual assault in their lifetime. [1] My apologies; despite the mistaken figure it's still a large number. This figure represents the number of women who will claim they have been a victim of sexual violence.
You are claiming that some (likely significant) portion of these claims do not meet your definition of harm or violence. I'm not looking to get into a pedantic argument here about what kind of touching counts as sexual assault, or how far an assailant needs to go before the victim is "really" hurt. All I'm suggesting you do is talk to someone you know who considers themselves a victim and try to understand why they do; I really think you might learn something new. All you've said so far is that sexual assault isn't really a big deal because you don't think it's a big deal -- something of a circular argument.
