So be it, we read what the OP wrote differently. If the daughter's husband is American then the culture difference may not apply but it is also equally possible that there are still cultural differences. My parents are first generation and we have different traditions than other American families who have several generations born and raised in the states. I have several friends who have either migrated from India or West Africa themselves or their parents migrated and they were born here. Though American they still live many of the traditions from those counties so there are still cultural differences. If you think that people who migrate to the United States immediately abandon their home country's traditions and culture you are mistaken.

What I wrote to the OP has nothing to do with race. If you want to keep pressing the issue and keep bringing race into this than those are your words, not mine. The only thing I will address with respect to race is that it is unfortunate that the step father doesn't agree with interracial marriage as that is hurtful to the step daughter and her husband. Hopefully there will be an opportunity for all of them to interact frequently and learn from each other, and the step father eventually changes his opinion. Please stop race baiting me because I have no issues with interracial relationships or people of other races. I also think you are making assumptions about me that may be incorrect...don't assume everyone you speak to online is white.
