Today it seems fashionable to accuse anyone who adopts any cultural trait from another of 'cultural appropriation' when in reality it's usually a case of transculturation. Transculturation us perfectly natural and to be expected.
For example, a white American raised in an African American community or who is significantly opposed to African American culture through radio, television, etc. will naturally adopt those traits. He may learn to enjoy jazz, learn the sax, learn to appreciate rap, etc. If he's raised in that environment, that's normal, natural, and not cultural appropriation. The same applies to an English Canadian who is raised in a predominantly indigenous community in Nunavut. He might learn the language and music, learn to make and appreciate the same dishes, etc. Again, it's to be expected. He might not even like his own Western foods if he's not used to them.
The French Canadian raised in Toronto might seem more English Canadian in his thoughts and behaviour, and the reverse for the English Canadian raised in Quebec. A French Canadian raised in Scarborough might even adopt elements of Chinese culture, maybe even learn the language. Again, perfectly normal.
A Canadian whose raised abroad by businessmen or diplomat parents might also not seem so 'Canadian' when he returns. Perfectly normal.
None of this is cultural appreciation. It's time those railing against cultural appropriation climb out of their caves and see the real world.
