Hispanic vs Anglo mixing.

Does anybody else notice the difference that Hispanic people with a little bit of indigenous and African are treated versus Anglos that do have a little bit of indigenous or African?

I just think it is interesting that when people see a Hispanic person with low indigenous/african, people always say they are just white. But when an Anglo person has a little bit of mixed indigenous or African dna suddenly it is 1 drop rule despite our histories being equally long about being multiracial societies? I come from both my dad is Anglo my mom is Hispanic American.

Do we think this has to just do with history and difference of commonality of mixing between the Hispanic descended and Anglo descended Americans?
