I have also seen women turn on a dad. I was in a park once when my sons were little, with my older son who was about two. There were about five moms there where I was with various kids; none seemed to know each other.
I let my son slide down the big metal slide without holding him, while I waited at the bottom . The slide turned out to be slipperier than I thought and he zoomed under my grasp and went flying into the bark. He was fine - it was actually funny. I laughed and picked him up and helped brush him off. He was wasn't crying or anything. Three of the women yelled at me in unison even though they didn't know each other, like I was some clueless dad endangering my child. I was a bit stunned by their overreaction.
I am normally very friendly, but after one wouldn't stop I finally turned around and told her he was fine, and maybe women needed to learn a lesson and let their kids experience a little danger for themselves without being coddled. I told her I was a great dad and dads just handled things differently than moms that kids need to experience some things for themselves so they can learn. One of the other ladies who hadn't yelled came up to me afterward and told me I was right on the money.
Come to think about it, she was hot. If I hadn't been married, I would definitely have pursued things with her.
