I was replying to your other post, but I guess I can do it here... I would argue that there's a reason those articles were written about the incidents. They don't happen as often so when they do, news articles like to highlight the incidents and pretend that they're the norm. It's not.
You posted 3 incidents of it happening - do you know how many kids are out there with parents _not_ getting harassed? A lot more I would bet.
