Does she also sell other objectionable things like images of kiddie porn? It’s called having a standard. Some folks would make money off their kids bodies, other people chose a standard to live by. It’s the great American way.
To equate child porn with an image of Obama is ludicrous. At the very least, you are trivializing child pornography.
I might boycott a company because the company has expressed a political or ideological alliance with Dems or Obama, but the image itself is neutral. In this case, some of the profits will fund the reelection campaigns of Jim DeMint and Tom Coburn. But this is none of the business of the Obama supporters buying her product, nor should it be their business.
