@Gaveston, did you read my post above? It addresses the concern you just raised again.
@Carol Channing
This is a good point, and an important nuance to be aware of. Many people from Latin-America are white, and some social-justice-minded people (including myself) occasionally forget that fact by lumping them all together, and considering all Latinx people “people of color.” When in fact, many people from Latin America are white, and they look white because they descend from white Spanish colonizers, rather than from indigenous cultures. And lumping the descendants of white colonizers into the same category as indigenous people is yet another form white-washing. So on this point, we agree.
HOWEVER, we know that the people in In the Heights are supposed to come mostly from The Dominican Republic, Puerto Rico, Cuba, etc. as opposed to places like Argentina where it’s more common to see lighter-skinned people. Plus, if we look at the actual makeup of Washington Heights (where I’ve lived for the past 2 years), the community tends to be made up of Black and Brown people, not White Latin Americans. So I think it’s safe to assume that the characters in the musical are supposed to be People of Color, even though — as you correctly point out — not all Latinx people are.
So then I would defer back to the earlier point I made about whitewashing vs. authenticity, but I’d amend it to specify that Black and Brown Latinx people are the subject of racism and whitewashing, not all Latinx people.
