Three points on racism in our society

The root of racism in our society: a few observations

1. The races that you can identify yourself to are: American Indian or Alaska Native, Asian, Black or African American, Hispanic, Native Hawaiian or Other Pacific Islander, White. Why mixing color, language, region to distinguish different people?Why we use color for White, region for African American, language for Hispanic? Wouldn't a fair classification be either: Black, White, Brown, Yellow or African American, European American, Asian American, Latin American, ...?

2. We use the word "white" to indicate good things and even a bad thing becomes apparently good when you add to it (e.g. white lie). And almost all black things are bad (e.g. black market, black list, ...)

3. The color "white" denotes to cleanliness, purity, divinity, etc. while the color "black" used as filthy, impurity, corruption, etc. You would find statements in religion like: the heart is clean like white and as you commit sin, the heart gets black spots and become black as you sink in sins .....
