Since anthropologists claim mankind moved out of Africa and spread throughout the world, then everyone can claim to be African-American and get a piece of the affirmative action pie
Most folks making a claim of special privilege for hispanics really don't know their history since EVERYBODY born in the USA was born in a part of NA which was subject to the authority of the KIng of Spain.
While employed by the federal government I regularly put in appeals of my categorization when the boss would send in a form every year saying I was something else.
They'd ignore it.
One law suit by someone demanding privileges and being denied those privileges where Hispanic status is at issue would seem to be ripe.
