Actually I'm not American.
I suggest that a very large % of Americans have no understanding of / don't want to understand the Social Democratic model of sharing and supporting each other aiming for a good quality of life for all. It seems to me many Americans see Socialism as Communism and that's of course not what, in modern terms, Socialism means.
I'm from a solid Social Democrat country. I've lived in a Social Democrat society / discussion all my life. At home my parents attitudes to everything was underpinnned by sharing, equal opportunity and all (of society) supporting each other. This framed my attitudes and values today; sharing, equal opportunity and supporting each other - Social Democrat.
Many countries today are Social Democratic and are peaceful, balanced, have a good quality of life, and quality medical care for all at zero to very very small personal cost. It works.
