You probably heard that Alan Simpson compared social security to "milk cow with 310 million teats" (some accounts have him using the word tits). Many idiots are offended. They range from the professional victim crowd to liberals who are cynically using it as an excuse to get a deficit hawk off the Obama deficit reduction commission.
Reportedly, Simpson has apologized. He should have just told his critics to go f*ck themselves. The image of special interest groups (even ones with millions of members) suckling at the government teat is an old and honorable metaphor in American politics.
