I've done, like, 150 job applications in my short life (no joke there, seriously), and usually they let you pick up to 2 different races. But my issue is, they don't let you pick both Caucasian and Latino. It's either one or the other for some reason. What is up with that noise?! I'm a little of both, and I like it that way.
So I guess what I'm saying is... I can relate :l I like being a mut.
I'm in the same boat with you... though, most of the paperwork I have to fill out has the "other" option for me There were times when there wasn't that option, and I would pick the one that was outwardly obvious in my case (I'm half Black, half Asian... I look Black since I have a darker skin tone); I'd pick Black if I'm not offered an "other" option And I can't say I've ever been offended by not having an "other" option.
The only reason they do these surveys is so they can have some idea of which population is higher. Not like it really even matters but people like to know. So refusing to answer because OMG OFFENSIVE QUESTION!!!! is really childish and not helping anyone. But them not allowing for a mixed heritage option is stupid too, because if somebody is, as in your case, half and half, then if they choose only one option they are being misrepresented. Imagine how many people are actually mixed but they are forced to choose one- the data is probably completely skewed! I would just circle both options and let the data collectors figure out what to do with it.
I hear you, I'm half Polynesian and half white. I used to mark Pacific Islander most of the time, but marked Caucasian other times for shits and giggles. Being brown, I always get odd looks when I mark Caucasian.
