There's absolutely zero evidence that guys raised by single mothers are somehow more feminine. Do you think of George Washington and Michael Phelps as really feminine guys? And of course, children need to be taught how to be good citizens and human beings but you don't need anyone in particular to do that.

And if more men learned how to talk about their feelings and problems, there'd probably be a lot fewer of them who are depressed and suicidal. These old tropes are just that, old fashioned stories.
