Much as with the above [your inability to see privilege and systemic racism as the same thing from different angles], this is a semantics issue where "appropriation" has been expanded far beyond the problematic context out of ignorance or straw man considerations.
No one is opposed to cultural exchange, and cultural diffusion is inevitable in a diverse free market. The whiny writer of the GQ piece appears to be a non-American who doesn't understand that "Redskin" is a pejorative, so I wouldn't really trust him to grasp the nuances here.
Right. We can dismiss whiney Brits. What do they know?
You seem to lack to the ability to distinguish clear differences in meanings. It is not like we are talking talking about nuances or ambiguity.
By definition, unearned privilege involves the granting of special favors, benefits, protections, and so on to an individual or select, restricted, elite group; benefits not available to most people. If something is available to all white skinned people; it is, by definition, not a privilege. Also, a privilege is something affirmatively present. It is not the absence of something.
Synonyms of privilege would be license, prerogative, or entitlement.
An inherent or inalienable right is not the same thing, because, by definition, those rights are the common birthright of everyone.
Institutional, structural, and systemic racism involve the denial of inherent or inalienable rights to racial minorities.
Every piece I have read on white privilege flat out states or implies that the absence of racial discrimination enjoyed by whites is an unearned privilege. That is not only ludicrous, it is immoral to equate a freedom from denial of rights with the granting of special favors, benefits, protections, etc.
Some also go into the subtler conveniences of being a member of the dominant ethnic or racial group in a nation, such as being able to easily find dolls for one's children or band aids and so on that match one's skin color. Are those things special favors limited to an elite?
I would suggest we are better off continuing to address structural racism and racial inequities, rather than blaming all white people for being treated generally relatively well by the government and legal authorities, and enjoying some largely unnoticed or overlooked conveniences associated with being part of the majority racial / ethnic group.
