Considering the hateful rhetoric that's come out of MSNBC for years, perhaps that viewer warning should have appeared in the past. 

The buttons included ones that read "Hillary for prison" and "Vote no to Monica's ex-boyfriend's wife in 2016." Maddow informed viewers, "You may find it uncomfortable. And so, you may not want to look at this stuff. But these are some of the pins that are being sold at the venue." 

Maddow continued, "But from calling Hillary Clinton a bitch, to the KFC special referring to her breasts and thighs and left-wing and all of those other things. That's part of the merchandise of the RNC." 

Certainly, using bad language towards people in public life or making vulgar comments is inappropriate. But that's never stopped the journalists on MSNBC. Former network anchor Martin Bashir in 2013 wished that someone would defecate and urinate on Sarah Palin.
