I'm the product of an interracial marriage. White dad and African mom. I've asked them this question several times over the years. Surprisingly, at least to me, most of the negative sentiments towards their relationship came from my mom's side. Post colonial sub Saharan Africa created a pretty tense atmosphere for foreigners. White tourists weren't really affected but people were almost offended when my dad asked my Mom's family if he could marry her. It alll turned out great in the end but there still is some tension. Mainly, because some of her relatives think she married a white man to get away. I always thought that the racial climate in the 80s in the US would have proven to be more of an obstacle. I guess one negative aspect is that sometimes, people would give my dad weird looks when he hugged and kissed us in public. At school, my friends were always surprised when they met my dad because I look black. It would get to me at first but I embraced it a long time ago. Most people weren't used to seeing a white guy with a bunch of brown kids. We joke about it now.
