"Things You Wouldn't Know If We Didn't Blog Intermittently."
Are you sure this isn't a joke? The separate but equal quip suggests it is.
if it is a joke, it's in poor taste. But considering who's sitting in the White House right now, I doubt it's a joke. Either way... yeah, it's racist. Simple as that. Anything that's based on race is, by definition, racist.
I think I would be more comfortable just declining the invitation, myself.
