You are entitled to your beliefs.
However, civil rights laws don't delineate specific racial groups, they merely state "race".
Civil rights laws don't delineate countries of origin, they merely state "national origin".
Civil rights laws don't delineate which sexual orientations, they merely state "sexual orientation".
"White" is a race.
"German ancestry" is a national origin.
"Straight" or "heterosexual" is a sexual orientation.
All three are included in the law's scope.
I bet if you checked with the Colorado Civil Rights Division, you would find cases where people had successfully brought complaints on the grounds they were discriminated against because they were white or male or straight.
In fact, if people think that because they are white or male or straight, they're not protected by the civil rights laws, they are skewing the statistics, and denying themselves the remedies they can legitimately avail themselves of.
