I think you were just a tad over-sensitive to a joke. Really. Or perhaps I am naieve because I thought that the picture was trying to say she was going to be another "hillary" type first lady, meaning the owner of the brass huevos in the family.

Until you posted your poison-spitting post, I had absolutely no thought that somehow the post had anything to do with the color of her skin, nor any sort of covert threat of harm to her husband....unless you count harm coming from HER, since, as we know...black widows tend to mate and then eat the male.
