Does anybody really think of Joan Baez or Martin Sheen, or Salma Hayek or Penelope Cruz, or Ted Cruz or Marco Rubio, as part of a "non-white minority"?
Ms. Hayek is Lebanese (Semitic) which is counted as white in the US. Most US Latinos are mestizo or mulatto, not white. Brown people have never assimilated into white culture in the US, Canada or Europe. In Latin America, they effectively “defined white down” to include as white anyone who was predominantly white (see Puerto Rico where most “whites” have considerable subsaharan African features).
