No shit it's PC to mock the fatties. They did it to themselves.  Friend, are you living on the same planet I am? PC has not nor will it ever have even a trace of reason. The entire basis of it is to keep things fee-fee safe so Hungry Hungry Hippo doesn't decide that she doesn't want to buy from store X or not use internet service N. Remember, it's political correctness, and politics is won by winning the fee-fees of others. Same reason any non straight-white-fit-male group has advocacy groups yet you will never ever see a "White Straight Athletic Males for ______" lobby; it's not politically expedient. /rant
