It was a frigging ad on a show.
If they had pictures praising Allah on their windows, then I would agree that some groups might find offense.
Hell, they could advertise on the Playboy Channel (or similar) for all I care. I am not worried about the clientele it will attract.
The two sides are simple.
One is saying, treat Muslims in America without hate and discrimination.
The other is saying, do treat them with hate and discrimination, demanding boycotts of a TV show being sponsored with the first message.
It's outrageous that whether to treat them with hate should be a 'controversial issue'.
It would be like groups boycotting advertisers on 'Cosby' because it makes blacks look 'normal', and an advertiser cancelling under the pressure.
