While it is a shame that such an ancient symbol has been so heavily tainted by it's association with Nazism, and I hope that someday it may be rehabilitated, the kid was a total idiot and got what he deserved. Context matters.
Pretty much this. The symbol might have been seen as one of a positive nature before WW2, but after Nazi Germany stole it no one can claim that it means this anymore. This student not only embarrassed himself as an individual, but also as a Jewish person. Tikkun Olam is great, repairing the world and fixing it's problems through social justice is a great idea, but...you shouldn't throw your heritage and your roots under the bus to accomplish that.
