I think that there is something of a difference between the predatory abuse of those who are forceful, violent or even grooming and taking advantage of children, and the kind of harrassment that KK is talking about.
Having said that, it is in the perception and impact on the recipient of the attention. In my experience (professional not personal), some people who have been exploited and abused in ways that are just not acceptable don't have lasting issues. Others who have been no more than touched innapropriately are left with long term issues that ruin their lives.
The media attention on the North Wales care homes and the Jimmy Saville thing is bringing up issues for people that have lain dormant for (sometimes) many years. A similar thing happened when Childline was launched.
What I'm trying to say, is that it's very individual, some people shrug it off and cope, others don't.
