Or maybe you're just a Latino that they've gotten to know personally. Maybe this is how they try to deal with their cognitive dissonance: they aren't ready to let go of their prejudice in general, but they can't really apply it to you (at least not fully), in person, so they seek some form of reconciliation in their heads, and this is the excuse that they come up with.
I don't disagree that they're bigoted and stupid. I'm not contesting that. But I don't agree that it doesn't really matter. I think it does matter, because it changes the scale of the problem. If you only have these attitudes in the abstract, but upon meeting and interacting with a person from whatever group you're bigoted against you find that you don't actually hate them, then the consequences are different and, I would suggest, much less severe than if you continued to hate them even after a personal encounter.
Going back to people telling you that you're the "right kind" of Latino, I would find that offensive, but isn't that reaction still preferable to one in which they still considered you the "wrong kind", believing that there cannot be a "right kind"?
I'm not sure that a bigot saying you are "the right kind" is necessarily better than blatant bigotry. Personally, it's easier when the bigot flies their flag openly, than those that put on a pleasant face. Actually, I am sure: being told you are the "right kind" is not better, it means the bigot is hanging on to their bigotry, and are willing to tolerate you for the moment.
My spouse and I, being interracial, see and hear what bigots say when they think they are with "their kind" about "the wrong kind", and it's not pretty. Even more sickening is seeing the face bigots put on when in the company of "the wrong kind." Is it better than blatant bigotry? Sure, in much the same way that its better when a cannibal uses a fork.
More generally (not in direct response to anyone), I see and hear explanations on how the bigotry here is not that bad and understand the motivations. If I were raised here, if this were my "normal," I imagine I could see what appears to be everyone getting along, little name calling, desegregated companies.
This is not my "normal," and I don't see people getting along, I see them not interacting with each other more than necessary. In the desegregated companies, I see no minorities above first tier management, little social interactions between workers of different races. It's practiced separation.
The kind, friendly, accepting, public face of bigotry is a thin veil. The different treatment my spouse and I receive in professional settings is astounding. The hostility when we are together is palpable. The attitude change when someone has been dealing with us individually, then together, is like night and day.
Bigots do not kick and scream when they see something they don't like. Bigots know that to make a stink, or even notice, is not allowed. It's forgivable that people think that this is acceptance, or not caring. When bigots think they are in "safe" company, the truth comes out. It's disgusting.
