Keep on repeating it - it doesn't make it true. Whether you acknowledge it or not, luck does have something to do with it and ignoring that fact is not only silly, it's dangerous.
You seem to be saying that if you do what you are supposed to as a parent then your kids will be fine. You seem to be saying that because you personally have not had any tragic or near tragic things befall you and yours that's some sort of validation of your parenting skills. While I don't doubt for one moment that you care for your children and that you are an excellent parent, I KNOW for a FACT that regardless of that, bad things can and do happen - even to kids of the best parents - in spite of their excellent parenting. Denying that is foolish - but continue to deny it if you must. I don't expect my point of view to change yours and you've made it abundantly clear that it won't.
As for me being insulted - I am not. I am saying that your logic is insulting. I do wish you the best and hope you never discover how truly flawed your belief that your parenting skills alone are enough to prevent tragedy.
