From http://utminers.utep.edu/omwilliamson/ENGL1311/fallacies.htm :
The Worst Negates the Bad (also, Be Grateful for What You’ve Got): The extremely common modern logical fallacy that an objectively bad situation somehow isn’t so bad simply because it could have been far worse, or because someone, somewhere has it even worse. E.g., “I cried because I had no shoes, until I saw someone who had no feet.” Or, “You’re protesting because you earn only $7.25 an hour? You could just as easily be out on the street! I happen to know there are people in Uttar Pradesh who are doing the very same work you’re doing for one tenth of what you’re making, and they’re pathetically glad just to have work at all. You need to shut up, put down that picket sign, get back to work for what I care to pay you, and thank me each and every day for giving you a job!”
Apparently the senator hasn’t been properly educated on how to think logically. But it sure has gotten him far in his life! Clearly our political class is rewarded not for being reasonable, nor correct, nor for pursuing truth, and definitely not for helping society; but instead for bullying, saying foolish things in public, appealing to the lowest common denominator, and distracting from the important things that are happening around us.
