I thought the "Buddy Christ" ones were funny because of "Dogma". I doubt that anyone who would actually buy that shirt or wear it has ever seen the movie. (which I, good Catholic that I am, not only own, but really, really like)
Anyway, the rest of the shirts were silly and the intent behind them is something that whoever designed them should be ashamed of.
I'm leaving for WDW tomorrow morning (happy dance!!) and the only holiday shirt I will be taking is my "Joy From the World" shirt from 2005. Provocative buttons and clothing really doesn't have a place there, whether political or religious. WDW is the place where we should be able to put all that stuff aside for a few days. We can all go back to poking each others sensitive buttons and insulting the opposition when vacation is over.
