I think you are overstating that, LTS. Sorry about your experiences: but one doesn't need to experience every misfortune going to have empathy with those who have suffered them; neither does such a lack disqualify one from expressing a rational opinion as to how they might best be avoided, even tho one might know that such evasive action is never going to be completely foolproof.   

To declare an interest ~ my wife was once screwed against her will while staying overnight without me with some old and, we thought, dear friends in London once. I didn't find out about it till after that friend was dead, so never had the chance to confront him about it. I still feel badly about the whole thing, and so did my wife until the end of her life. But I don't feel that this experience at, as it were, second hand, gives me any more right to express an opinion on this thread than another guy whose wife was never thus taken unwilling advantage of. And so on, right up to those who have had the genuine, full-on misfortune we are discussing.
