dealing in absolutes...
...making blanket assertions is never a good idea. I'm certain a small percentage of American women may be reflective of your opinion. However, the vast majority of us thrive on being ourselves and exuding not only natural, caring qualities, but also sharing our intellect, sense of humor, and more...
If I flipped your statement over and stated that American men are ego-centric, assholes that should be avoided, you'd more than likely tell me that I'm full of it, yes? Certainly, a small percentage of men are ego-centric, assholes, but the vast majority are not.
