It wasn't the ethnic mexicans it was the bitch ass spanish that was in the slave trade. more mexicans have black blood those afro-mexicans are pop. of blacks who haven't intermarried extensively. Why do Mexicans feel like they the only Latin country that escaped black mixing. All latin countries had fat ass slave populations in there shit, gettin they fuck on, except for shit like Argentina. But the thing is Mexico had one of the strictest caste systems, racial class systems, that said who could fuck who and if you had this amount of blood in you then this is what you could do and your position in society.
