"Men just need to grow up."

I absolutely agree. See my article "Why do men pretend to be more rational than women?" to see how much I agree.

Except for the word "just." Because growing up is never "just" growing up. It's difficult and painful, and some boys and young men get discouraged and give up for reasons having to do with mental health and other problems.

Which doesn't make their behavior or attitudes excusable, but does make them a little more understandable.
