Maybe saying "beautiful" was a bit too dramatic.
But the world has a lot of problems. It definitely isn't "beautiful" in all ways. And I think that the expectation of men to be "cool" or dominant, powerful and strong. And treating them like they're less worthy, is another thing that makes the world a little more sad. Unfortunately, there's all sorts of things that make the world a little more sad and a little less beautiful. "Beauty" in this case, doesn't mean physical beauty, but something more similar to harmony. For instance, a world with less needless violence and meanness, is a more beautiful world.
But again, that might be a too dramatic way of describing things.
