Were there any ways in which European settlers in British North America could've more strongly and willingly accepted a MESTIZO-style society of interracial marriage and ppl of mixed blood, similar to the situation in Spanish and Portuguese colonies in South America ? Of course, there were interracial unions between many ppl of different races, white, black and red (so that many white or black Americans whose ancestry is traceable to colonial times, can claim Cherokee or other Indian blood), but how could such relationships and the resulting progeny- esp between black men and white women- have been viewed more positively by Anglo-American society, instead of being shunned and frowned upon ?
