You know we could all dig up some really crazy, offensive shit that the Republicans have said, and their loudmouth pieces like Rush Limbaugh, but no one has ever demanded they be fired or make apologies. This little tweet by an MSNBC staffer is not that egregious in my opinion, and to a certain extent is spot on with all those Republicans and RW's who were upset at this Cheerios ad to begin with. Some of the most hateful things were said on Fox news about it, but not one person was fired, nor did the Democrats say they were going to Boycott Fox news.
This is just petty immature, typical crap from the right... as usual.
