I should start teaching my 2 yr old son now that he is very likely to grow up as a sexual predator who is just waiting for the chance to attack girls and women (because obviously the statistics show just that)
No, the statistics show that the vast majority of violent crime and sexual crime is committed by men. That is not the same thing as saying the statistics show that all men are sexual predators or even that most are.
I believe that the vast majority of men are nice decent people however that still doesn't mean I'm not going to be more wary of being alone with a strange man than a strange woman and for good reason too.
Men tend to be bigger and stronger than women so if a man decided he was going to attack me then I would have no to little chance of stopping him. However if a woman decided she was going to attack me I would be in a much better position to stop it or escape because the balance of power an physical strength is more equal.
even if he doesn't choose to take the route of being a sexual/violent attacker he will still make most females feel extremely uncomfortable just being around him because he was born with a penis!!
Making your son aware of how he might make women/girls feel is actually a valuable lesson for him to learn and I really don't know why you're dismissing it or trying to make out like it's silly.
I know if DP is walking behind a lone woman at night and there is no one else around he will either drop back and wait until she's out of eye shot or he will cross the road so it's clear he's not following her. He does this because he knows that having a man walking behind you at night on a deserted street can be intimidating and scary for a lone woman.
Now my DP is not violent. He is not a rapist or a sexual predator. He knows that and I know that. However he realises that the woman he's walking behind doesn't know that and he doesn't think it's fair for her to be scared or worried. So he takes a few minutes to consider how she might be feeling and acts accordingly.
So yes given that when your son grows up he is very likely going to be bigger and physically stronger than most women then teaching him to take into consideration how some women might feel is the right thing to do.
