TV and movies aren't always an accurate reflection of who people are and tend to be an exaggerated reality at best. American men and how they are raised vary wildly from family to family, whether they are raised in the city, suburbs, or out side of cities, and is different from state to state. There are generational differences too. Younger men from the current adult generation do not act the way younger men did when I was first married.
What are your factors to determine if a man is masculine? I bet your definition and mine would differ to a degree. I consider a man who works hard, is smart, handy/able to fix things, and provides for his family as masculine. I think that those traits can be found in any country and in many men.
