Cultural appropriation is a system to justify offense of differences. Which is the more offensive? Adele wearing Jamaican colours, or Dick Van Dyke trying to do a cockney accent.

These type of people will turn someone else's opinion into a grudge, and put it in their rucksack until it turns cancerous and eventually fades away, thus leaving space for the next grudge.
