That's why it's important to challenge these shit flingers as loudly and publicly as possible in every possible forum and venue. Otherwise, by sheer repetition, the shit sticks.

Seriously, shit sticks. If you don't do anything to hinder the bad guys, they win. Don't be afraid to voice your opinion -- and be prepared to take a stand for it.
