The need for a guy to be strong went out with the invention of the handgun.
To a degree, yes. While there is less of a need there is still a strong desire among women for a man that is in fact, a Man. When I was a bouncer in a disco I had a guy tell me that my muscles didn't matter because all he had to do was pull out his gun and shoot me.
I thought he meant to do just that and so I simply grabbed him and squeezed him like the zit he was and told him as the pressure on his ribs became greater and greater that a gun is kinda useless if someone like me tore his pipe-cleaner arms off. Am I lucky he didn't shoot me? Yup. He is luckier I let him go so he could head home and change his pants. Whether or not you believe me is irrelevant. My younger brother was there with me and he knew exactly what the fellow was going through as all my brothers used to taunt me although never with the threat of shooting me.

But again, what you said is correct to a degree, my friend.

And for the record, just like in the first Captain America film, a weak man knows the value of strength and knows compassion.
