There have been a few subjects I've planned to post in this thread, not had time, still extremely busy, so I apologize if this is unclear, blunt, etc., but one point I'd planned to make is addressed in this c/p from a Psychology Today article:
Culture. (Noun). The sum total of ways of living built up by a group of human beings and transmitted from one generation to another.
Though the definition doesn't elaborate, "the sum total of ways" is usually presumed to include language, food, dress, music, and holiday celebrations, as well as less clearly defined concepts such as values, shared points of reference, and norms regarding how we interact and relate to each other.

With all that in mind, perhaps someone who believes 'Black culture,' 'White culture,' 'Asian culture,' etc. even exists may want to consider it from some examples:
1. Thinking of two individuals I know- one person is a multi-generation descendant of slaves (Africa), one is a second-generation American of Caribbean Island heritage. They grew up in two different parts of the U.S., and are members of two different generations. What 'Black culture' do they have in common?
2. Thinking of two other individuals I knew long ago, both "Asian"- one person escaped Vietnam during the Communist takeover, when I met her she was 30 yrs old and had been in the U.S. only a few years; the other was born in the U.S. to a Chinese-American doctor. They too were members of two different generations, and lived on opposite coasts. What is their 'Asian culture'?
3. The concept of 'White culture' is even more mystifying- considering how many countries around the globe are predominately white, what do they have in common with each other? I'd venture to say "not much." As random examples, a person whose parents or grandparents came from Russia has little 'culture' in common with a person whose parents or grandparents came from England.
I don't mean to diss anyone or anyone's viewpoints, but in my opinion attaching the concept of 'culture' to a race or other inborn factor (ethnicity, etc.) is ridiculous. I believe if 'culture' exists at all, it's based on where a person is from, where he/she grew up, the ways the person absorbed in his/her early environments, etc.- and their race has virtually nothing to do with it.
