Time for Some Veal
PETA airs commercials comparing meat to the Holocaust. In Germany.
This reminds me of the anti-Issue 3 ads comparing it to Klansmen and Nazis. I was teaching Freshmen English at the time and several otherwise liberal students wrote angry gay-bashing essays in response to the ads.
I'm not arguing one way or the other but I have personally observed how commercials like that backfire.
