I would be inclined to say that a shirt showing an aborted fetus would probably be inappropriate to wear in in school (although I strongly believe that these images, however upsetting they may be to some, should be seen by high school students). Short of that, I fail to see the problem. What I find most alarming is the fact that it is now "fashionable" for students to wear shirts with pictures of Che Guevara, who personally murdered hundreds and was responsible for the death and torture of thousands; however, I have yet to see wear schools are banning these shirts.
