Yes, that's the whole point. It basically implies that girls are inferior to boys. If a girl screws up or does something poorly, nobody ever tells them the are "acting like a boy."
Oh, come on. Seriously?
It implies no such thing. It simply acknowledges the fact that females generally have a weaker throwing arm than males.
I've always understood that I differ from men in all kinds of ways, including size and strength, but I have never felt "inferior."
Hah. I have heard, “You are acting like a man” many a time. It was not a compliment.
That’s not what it means at all. I hate to break it to you, but on average males are taller, bigger, stronger, faster, and generally more athletic than females. That’s nature, not an insult.
Nobody bats an eyelash if someone says “This needs a woman’s touch,” or “Men are insensitive” yet even in an era when women are strong and we can hear them roar, we still dare not say anything that might upset their delicate self esteem.
