I am nothing but cultural appropriation. From my head to my toes; from birth until today. I don't expect that to change and I will never feel guilty about it.
You should be proud that I value your culture enough to "appropriate" parts of it. I'm not going to copy junk.
All human ideas, inventions, and such are available for us ALL to incorporate-- or "appropriate". We are all human. We can even incorporate "culture" or whatever from other species if we want. It is your right as a sapient being. Don't let any idiot make you feel bad because they tell you otherwise. They are lying.
You have an entire planet, and hundreds of thousands of years (at least) of ideas and clothing and art to choose from. Pick the good. Reject the bad. Make yourself the best you can be.
Dare you appropriate the Crow-Magnum Man's culture?
