Ethnically Ambiguous (I feel like I have used this title before)

I have a friend who is going to teach a class on privilege this semester.  She told me about a task that the class was going to do together.  She would say something like "wouldn't get a loan based on the color of his/her skin," those that didn't have to deal with that would step forward.  I stopped myself from saying what was an obvious issue to me but of course to 100% Desi that she was, it wouldn't be.  What if you're mixed?

I have a 50/50 chance that people will think I'm white.  I would have no idea which way to step if asked these questions because it honestly depends on the person I come in contact with.  For example, my supervisor thinks I'm Jewish while my coworkers think I'm Latina.  Yes, I know, but it is happening!!  If there is ever a problem, I'm always questioning whether it is race or not.  I have to really listen between the lines when someone talks to figure out what they are taking me for.  Another example was when I was talking with a resident who is white and she said that this neighborhood (historically Hispanic) was becoming more white.....professional, urban.  Guess what she took me for.  (If you guessed brown, you would be correct!)

I know I have more privilege than most because my skin is lighter, but knowing actually when I have privilege is up in the air based on the person.  I didn't feel like I could bring this up to my friend because I don't know many like me.  While interracial relationships are becoming more acceptable, the children and grandchildren of those relationships haven't been as accepted.  We are a minority within a minority and our voice is almost never heard.  I really don't know many people in my position.  (My cousins tend to be on one end of the spectrum or the other, they don't have to deal with being in the middle)  I love being mixed.  I love all the countries that I come from.  However, I know it would be easier if I was from one country.

As I have grown up I have realized this is a very American issue because Latin American and North African countries don't have this issue. (90% of them are mixed!)  I am a little jealous of them.  They don't have to feel gagged by this issue that should be a none issue.  Am I wrong?
