I get that. My comments are strictly within the context of the OP about what would happen if you just lie. If someone rejected you for claiming `asian`, for example, and you have an immigrant great-grandmother from <asian-country>, you would be able to challenge it.
I'm saying they can not prove one is lying because there is no way to be formally classified. I pointed out one of many low hanging fruit ways an argument can be made from the links the other posted included. Being a more creative type, and having money with time to spare, one could find a way to argue whatever race they wanted. Even people with stricter bounds for themself are likely to find a trail of DNA and/or lineage for many of the cherry-picked classes on those forms.(especially in North America)
