Rape was a felony criminal act when I was young, so my use of the phrase "boys will be boys" wasn't meant to excuse rape then just as it doesn't now, although it's unsurprising a criminal defense attorney might argue that it does.
You misinterpreted my post - I have never heard of a defense attorney arguing this, and much less of a judge or jury accepting it as a valid defense. The example was to illustrate the gap between reality and the "rape culture" some assert we live in.
