I know some lovely men, my partner is one of them. But he would absolutely not hire a male babysitter. He’s aware that most of these crimes are committed by men, so why wouldn’t he just hire a woman?
The fact that he is a good man, means that he doesn’t take offence that many parents would prefer their children looked after by women. He understands that it’s not a personal attack on him, just a sensible precaution based on statistics.
