The number of fathers that gave me shit for taking care of my kids is ridiculous. We had our kids 15 months apart and I would routinely have both of them in a public restroom for changing. The pure vitriol directed at me for doing the womens job was immense beyond measure.
On the flip side, when I would take them to the park to play, I would be acosted by nearly every mother there. There were no fathers, just mothers that would have to comment that it was great to see a father participate. I also got a lot of phone numbers that I got very embarrased about and my wife found hilarious.
TLDR:. Most american fathers do not put in much effort unless its sports related.
