It wasn't humor and that's not a valid excuse. Someone being mean or racist to you doesn't give you a free license to be racist or excuse it.

2014 my well sweaty b****. Is what's shown in the op her entire body of work, or just a sampling? Regardless, this spans almost 27 months. Aug 2013 - Nov 2015. It's not like she farted at dinner one time and apologized for it. She farted right in people's faces, with purpose, for over 2 years. Often times at dinner. As far as time span goes, this wasn't a blip. In the less than 3 years hence, not 4 years, she may have developed a sense of professional self preservation, but there's no reason to give her credit for anything other than that. Is there? Did she even attempt to own any of this before she was forced to?

Passing that off as satire? That's the worst, objectively worst, satire I've ever seen. If I were having dinner with her, and she started trying out her satirical material on me, I'd rather she just....i dunno... fart in my face. And this is at dinner mind you. Terrible satire. Terrible excuse. And she brings up the C word, as if the lack of C is the missing piece of the puzzle that will make me go, "Oh. Ohhhhhh! I get it now! You're a fucking racist on Twitter.......because other racists made you a racist too? Theeeenks! At least I know why you're a racist C word!" That's the context I guess. And/or she's one of the worst satirists in history.

I know you tend to do this to put yourself in the center of controversial topics but still..

So this is not racism?
Dumbass fucking white people
oh man it’s kind of sick how much joy I get out of being cruel to old white men
#CancelWhitePeople
white men are bullshit

What about this?
Dumbass fucking black people
oh man it’s kind of sick how much joy I get out of being cruel to old black men
#CancelBlackPeople
black men are bullshit

Overgeneralizations can be racost but not all of them are. The jokes made by this women aren't racist.

She was making jokes and counter trolling so if she directed it at Blacks it wouldn't be racist. It would still be in bad taste but not racist.

Regardless of whether she actually means it or not, she's not making these types of statements in 2018. I can't really give you a reasonable timeframe for when these types of actions are okay but she's not making them in our current political climate. The statements she made were awful, but there has to be a point in time where people look past the mistakes they made and try to better themselves to make sure that they don't express that type of vitriol again. If we keep slamming individuals relentlessly for stuff that they said in the past, we won't be able to change as a society or better ourselves as individuals. Her apology didn't seem bitter and it seemed like she was truly ready to learn from her past occurrences. There has to be a point in time where a person is given a second chance to grow and mature. 

If there's a market for Hannity, Tucker Carlson, and Alex Jones, there's probably going to be a market for the "hate whitey" crowd. It's all feel-good entertainment. Yay for free markets?

Prove it, don’t just assert it and call it a day. Saying “white people are bullshit” and describing white people posting on the internet as “Dogs pissing on fire hydrants” are racist. Those are demeaning and dehumanizing over-generalizations. If I were to describe any other race the same way as she did, I would receive a lot of backlash, too.

replace the word white with black, reread tweets and tell me its not racist.

I appreciate your well measured, fart free response, but I really don't think there's enough of a difference between 2013/2015 and 2018 to make any kind of distinction between what was unacceptable to say then vs what is unacceptable now.

As for the rest of your post. Sure. And I'm not saying that sarcastically. It's a good way to think. It's just that: It was so recently. It went on for quite a while. This was a THING with her. She was around 27 when this ceased. That's an adult. Well into adulthood. As far as her sincerity in apologizing: I have no idea. Like I asked earlier: Did she try to get out in front of this at any time before it became public knowledge? And I'm not including the "candid" conversation she had with her then prospective employers at the NYT during their "vetting" process. Or was this only addressed when she had no longer had any choice in the matter? Honestly, I don't think she deserves to work in journalism. I hope it ends up that she's forfeited that privilege. I think she should be able to be a musician. Become an astronomer. Pump gas. Whatever. But not work any job that involves the public trust. I hear you, and respect the compassion, but......I really hope she loses her job for being a racist dumbass. There are worse fates out there, many of them thrust upon less deserving individuals.

She is awful.
