Sorry, I don’t see where he says “with a 20 year old guy”? You think a guy has to be 20 before a girl can get pregnant?? Maybe you need a biology class, not a dictionary.
If you read the article, that is the average age of the guy who has sex with a 12 year old. It isn’t a couple of 12 year olds messing around and going too far...
And 20 or 13, it is still below the age of consent, isn’t it?
And in any case, saying ‘it is a mistake in my opinion for a 12 year old to have sex’ encourages those 20 year olds who are typically the ones engaging in sex with 12 year olds - probably because they can be taken advantage of easier than an older girl.
Sorry, but a decent man would have said, “If anyone messes with my 12 year old daughter, the bastard will learn my REAL feelings about gun control!”
