We are mutts, long and short.
People in Mexico are mutts, Central and South American are mutts. Caribbean are mutts.
In all areas their are clusters of true indigenous people.
Further although we do have Spanish their are French German and mixture from Africa during the moorish occupation in Italy, Franch and Spain (before it was Spain)
People have conquered raped and pillaged one another for centuries.
What is a trip to me many Central Americans/South Americans Etc. have a hissy fit when you accidentally ask "are you Mexican"? then go on a tangent to insist they are NOT! Blah! Blah! blah! I just say get over it! we are mutts, Europeans are mutts, someone has begat this and that during a time years ago and it will continue the big mix, so grow up and open your mixed up mind!
