The French and Spanish (Catholics) intermarried with the AmerInd. Not only for the reason you mention, but because it was not forbidden piously. The English however did not and it was considered a taboo. During this era, the 7th Commandment was understood to mean 'not to racially adulterate'. The interpretation can be easily verified.
The British definitely formed families with them and typically went back home to formally marry a white girl after several years. There's a famous case in Canada where the son of a white guy brought a case against his Dad. IIRC they made him pay support to his former common law wife.
That's not what I said though. I said it was it was considered taboo by the English. This was due to their religious mores. There were indeed instances of intermarriage, but these English were chiefly ostracized within the community. Contrarily, with both the French and Spanish, it was far more prevalent. Both these countries were heavily influenced by Catholicism, which teaches the 'Universal man' doctrine. This was not prevalent in England and several other northern European nations.
