Sheesh, why are you taking this personally? If a generalization doesn't apply to you, it doesn't apply to you. That's how generalizations work.
I'm not on this planet to bolster the sagging ego of any man, even if he happens to be my husband. That doesn't make me "unfit" to be a wife or mother, that doesn't make me "ungrateful".
When a women gets married, and she is grateful for the sacrifices her husband makes for her, he will feel appreciated and his ego will be boosted and he will move mountains for his wife.
But, principles are principles.
Sheesh, you make blanket generalizations and then are surprised when every woman on the thread, generally a majority, a GENERALIZATION of the population of FR, OBJECTS to your GENERALIZed comment. You made the declaration! "American women are ungrateful to the great American stud. American women are too manly! I, fatalis have spoken therefore it is the truth!!"
Expect to Suffer. Kind of like if someone came on and said that American men who marry oriental women have smaller penises. You know, a generalization. Only if the shoe fits. That sort of thing.
See how easy it is?
Why do you keep avoiding the question on who defines "grateful" and "appreciative."?
