I do not see the difference between having a poster of the president as a devil and just walking around saying you hate Bush. Both are on the same low education level. Saying you hate bush is really not any worse. Basically they could be construed as freedom of expression or as hate speech. Depends on your point of view. It is like saying all republicans want to poisin the air, starve your grand parents, and get rid of the school lunch for your kids. If you do not have to quantify your remarks they are just political statements with no basis of fact or reason.
As my old English Teacher would say, Prove It!
Personally I think both tactics are wrong. Saying you hate bush is wrong because hate serves no purpose. It only breeds violence. Making maliscous posters is an expression of your Hate. Hate does nobody any good in the world. Hate is what makes people biggets, Hate is why people killed the Jews, Hate is the root of Kosavo.
Hate breeds Fear. What we Fear we want to kill!
As far as discipline goes, Making a preson write a 5 page report on why they hate Bush would be appropriate. This way the person has to give a line of reasoning for the Hate. Hate is inherently evil.
