The image is excessive and over-the-top. That much is made obvious by the number of people who look at it and jump to a half-baked conclusion that it is intended to be racist, anti-Obama, &c.;
I am disturbed that anyone thought this was a good idea.
I'm also disturbed by how many people are too witless to look past the superficial form of the image to parse out its meaning.
For crying out loud, people, the branding iron reads "UPPITY LIBERAL"!
