Should Tattoo Art Be Taught In Grade School?

I just heard of an art teacher that one of her projects she teaches her 4th graders about an African tribe and then one of their choices of "hands-on" activity is to draw a tattoo design because the Africans have tattoos. I immediately wondered if some of the parents might find this objectionable that their 4th grader is role playing a tattoo artist or in any way glamorizing the process. Then I asked myself if my child came home one day from school and showed me their "artwork" that they made and wanted it to be permanently embedded in them, I would be highly upset. I understand that they are attempting to teach the kids about culture and art, but I would ume their would be a plethora of things in the African culture as far as art goes that could be focused on besides tattoos. No matter how slim a chance it may be, if a grade school art project ends up being the thing that "planted the seed" in a youngsters mind to get tattoos, I think would be a shame and not what our educational system should be about.
