Everybody remembers learning about how certain groups of Europeans (Irish, ethnic Jews, Greeks, Romani*) weren't seen as "white" for a big chunk of change, but eventually came around and fell under the umbrella?
That's sort of what's been happening with the Hispanic population. It gets weird because Hispanics run the skin tone gamut. Brazil's a pretty interesting read on how your "race" is tied to skin tone and career. I.E. a light skinned, mixed race lawyer is "white" because of his job, but the same complexion on a construction worker might make him black.
*(Hasn't happened for the Romani yet).
Anyways, fuck all these shooters and their manifestos.
Some asshole writing a manifesto is some asshole hoping someone reads it.
Put them in a unmarked grave and be done with it.
