It's one thing to tell a joke, and it's another to turn it nasty. For example, the camel joke, followed by the reply: "I feel well qualified to say there is no such thing as too many Catholic-bashing jokes."
I found the humor in the joke, but saw the incredible ignorance in the above quoted reply. I went through Catholic schooling about 9 years later than the author, and now maybe I feel qualified to say that only someone very weak of mind could have their conscience permanently scarred by such schooling. My assertion is as ridiculous as the quote, of course, but I said it to make a point.
I would agree that telling a joke "against" any group without malice may be funny, but isn't the telling of it in and of itself potentially malicious?
And, no, I ain't the most PC person... believe me. I say lighten up and learn to laugh at yourself. At least that's what I'm trying to do!
Now, having just watched Family Guy, I know that Santa Clause isn't Asian. I know it's true since Stewie said he can't be because he isn't driving 20mph under the speed limit with his blinker on! And, if you've ever used your ironing board as a buffet table, you might just be a Redneck!
