I suppose you need to define who are "good, real Americans".
I will offer my opinion on what defines a "good, real American" below:
- S/He judges people by their character, not their color / ethnicity or sexual orientation
- S/He respects the laws and the American Tradition of Jurisprudence - no one is above the law and no one should be judged guilty until a trier of facts finds evidence beyond a reasonable doubt.
- S/He who supports and defends the Constitution in total, including the vision left to us by the framers as outlined in the Preamble
- S/He support aid and comfort for the needy: the aged, infirm and children
- S/He who supports Public Schools whether they have students enrolled or not, for they are the future
- All those who support equal rights and equal opportunities for every citizen
- None of those who are liars, cheats and violent criminals, those who do not support the traditional values, mores and ethics Americans have always articulated and too many ignore.
