Do you feel raising only boys or girls has or can change your view of the world?

My mom use to say with boys you worry about them getting in fights or ending up in jail and with girls you worry about them getting raped or knocked up.
I have a friend who seems bitter towards men and she has raised only girls. She seems to think everything with men is black and white. I sometimes wonder if her bitterness comes from her personal relationships or is it from raising only girls.
I wonder because I have raised both a boy and a girl and before having children my thoughts about male behavior were one sided. Having raised a male, I realized that everything isn’t black and white about males or females.
