I am actually more interested in the treating people equal and not treating people special than the definitions. However, I know that definitions are important to some people and they will get hung up on them so I attempted to get what I could think about those things at the time out at the beginning.
I didn't say culture was or was not necessary. It is ideas so of course it is necessary. Mentioning taboo does point out something worth saying. Not all ideas are good for us. There is good and bad in most cultures. Fortunately we can and should take what works and incorporate it into our own personal culture.
There is no such thing as cultural appropriation. All culture builds upon the cultures (ideas) that came before it. There is only cultural appreciation.
Cultural Appropriation is mainly the same mentality that lead to classes on microaggressions. Training people to be constantly on the watch for things to choose to be offended by. They seem to forget the choice part though. They think people are somehow reaching into their mind and forcing them to be offended.
I agree no one can make anyone do anything.
