Thank you for the explanation. Yes, I'm brown. :) Although I know a little bit about US politics, I don't know much. This was clearly a case of misunderstanding on my part. Cheers.
don't sweat it. over here in the US, we're still paddling in an age where racism and genetic (perceived) superiority are making an ugly comeback to mainstream politics. you'll have to forgive the ones who are on edge about it.
