Would you want someone who created "art" featuring crucifixes submerged in uring and religious figures out of animal excrement acting as the voice of conservaitves, the Republican Party, or Free Republic and would you want these pieces of "art" associated with you? You are dead on comparing this sort of "art" with what was posted on this web site and I, frankly, want to be associated with neither. The appropriate response to bad people is not to show that you can be as bad an offensive as they can be. "They are as bad as we are!" That's not something to be proud of.
I don't know anyone who would want to hire a person with this skeleton in his closet. Then again, I don't know if an employer could legally use this as an excuse to refuse an applicant a job.
