Ucb, with my kids, we had multiple requests over the years to verify their ethnic or racial whatever, as the k-12 needed to present reports to the feds. I just think calling this some historical limitation is a stretch, in this day and age.
Bottom line, OP needs to be able to show, not just tell, that any Hispanic influence has shaped his perspective and identity. It may be subtle, but CC often agrees that just living somewhere for a generation is not it. Asians who lived a genration in S. America are not Hispanic. And frankly, the jury is still out on whether recent ties to Spain do it.
