Hispanic is not a race ,it’s a culture.
You can be white(European decent),black , Chinese , native south American Indian , or any mix above and still be considered Hispanic if you came from a Spanish speaking country.
I know this ;) cause they always marked me Hispanic too because of my maiden name (grandfather was born in Spain to an English mother and half German half Spanish father - so Spanish last name ) BTW I was born with red hair , I have very white skin and freckles ,speak with a southern accent (don’t speak Spanish ) and they still mark me as hispanic yet when I tried to get a minority scholarship they told me I wasn’t HISPANIC enough ... go figure =P
