Am I really caucasian?

What difference does it make? You don't have to answer those questionnaires, even on job or college applications.

I am what Hitler would call Aryan by most standards. On the other hand, I have a genetic condition most commonly found in Africans.

Spanish can still be Caucasian/white. It can be anything, since it's a nationality not a race. If your background doesn't' include Latin America, then you are not Hispanic.

You are most likely Caucasian. But to be honest, nobody is really just one race. Everybody has some type of mix. Also "Equal Opportunity Employer" is not real. They have to say that they are, because of the laws, but the sad truth is that people still get turned down for jobs based on race, religion, gender, etc. There has been a lot of research to prove that most employers are more likely to hire people with lighter skin. As sad as it is, it's probably in your best interests to mark that you are Caucasian.

Oddly enough, Spanish are not considered Hispanic.

No you are a slave to the goverment

just put black and see what the reaction is ..
