I just don't know what you mean by "corners." Even metaphorically. We live with each other. We depend on each other. We are constantly influencing each other. Both men and women would collectively fall apart without the other, right?
And "men/women" isn't some kind of club where we can all get together and "sort ourselves out."
It's easy to throw out comments like this because they're easier than showing actual compassion for each other.
