This juxtaposition of maps (top of the 2012 election results vs. bottom, the slave vs. free states prior to the Civil War) implies that the people in red states voted with the collective-vestigial mind of the ante-bellum south: the idea that a vote for “not Obama” is the equivalent of thinking that blacks should still be slaves. Perpetuating this image as a "stop and think about it" moment is not only a bit dismissive, but further, a serious slander of near half of the population of the United States.
What might have been a funny quip based on image correlation is shamelessly offered as causation; this conveniently furthers the hateful narrative that people who don’t think Barack Obama is a good President are racist.
I’m not racist. I’m disgusted.
