Hispanic, Latina, Spanish, Mexican

EDUCATION 101:

1. Does saying Hispanic cover all the above, as is it one in the same? I once asked a Puerto Rican if she was Mexican, and she got offensive, so I'm asking where bullets won't fly.

2. IF they are not the same, has anyone found a mix or product that drives a Mexican, Spanish, Latina in sane in a GOOD way?

Thanks X 2!
