Being a marketing professor, this commercial was already on my radar. Personally, I don't find it all that controversial, and I don't think most Americans will, either. But I do admit I noticed the biracial aspect right away and replayed the commercial just to see if my eyes had not deceived me. What I found surprising about it was that the advertiser chose to use this particular "hook" to get attention.
I am all for anything that encourages the melting pot, including biracial marriages. The most robust people on earth are those who are the product of diverse genes, as opposed to those who are the product of genes from the same tribe. That tells me God prefers biracial marriage as well.
It is the Democrats and liberals who are constantly trying to divide the country along racial lines.
