Well what does that tell you? It tells you CNN was probably looking to get rid of her anyway and this little fiasco provided them with the perfect excuse to do it. There is no grand conspiracy against leftists Cutlass. Leftists have been the mainstream in media and entertainment for quite some time now (at least 20 years, likely longer), so it's kinda hard to play the persecution card when you are the mainstream.
What job does Nugent have? More specifically, who is his employer that has the power to fire him?
Because they were smart and chose to work for organizations where their "brand" would be profitable. Remember, you can be as offensive, bigoted, and crude as you want in the US as long as what you're doing is making money for someone.
Am I supposed to feel bad for her? This very same thing happens to regular people every day when they make just one mistake at work. Difference is, those regular people don't have the a fat bank account to fall back on like Griffin does. So you'll have to forgive me if I don't shed any tears for a washed-up comedian who wasn't all that great to begin with because she destroyed her own career on a stupid PR stunt in a desperate attempt to stay relevant.
If she's smart enough and talented enough, she'll find a way to keep her career going. Hell, all she has to do is start a YouTube channel. She'll have to watch what she does on there as well though, what with all the new "advertiser friendly" content rules.
