If you ever use the construction "I'm not a _____, but....", rethink what you're saying before you say it publicly. "I'm not a bigot, but Muslims at the airport scare me" is an asshole thing to say. And so is "I don't hate fat people, but boy howdy, I sure don't want to have to look at them!".
OK, that's not an exact quote, but it's pretty much what Maura Kelly says in that piece. I'm sure she struggled hard to find the right words to get her point across; how sad that the point she actually got across was not the one she thought she was getting across. But then, it's so often amazing to see an asshole shouting from the rooftops without ever realizing that what they're shouting up there is actually, "Hey! Everybody! I'm an asshole!"
