As for that movie, BSo...
I'm Jewish, so obviously that movie is a very touchy subject, and obviously tattoos are hence a very touchy subject for a lot of people with close ties to the Holocaust. BUT, on the other hand, I don't think it's necessarily something that anyone should be trying to push on others. Like it or not, like iflit said, tattoos have become a part of American culture, beginning as an act of rebellion. The origin of them had absolutely nothing to do with the Holocaust, and nor does their creation as a part of American culture. Tattoos in this sense are not forced upon people, but rather a form of artistic expression. I understand where you're coming from, but it's sort of a completely different issue, in general terms.
A work of art is an invitation to love.
