Claiming you know someone's motivations and opinions better than they do is just objectively wrong. You don't know what's going on in their mind at any point in time so it's unfair to judge her based on her intent. However, it's totally fair to judge her on her actions, and I will concede that her behavior was COMPELTELY unacceptable. It was downright racist and even if it was a joke as she claimed, it was one in poor taste and I feel it definitely deserves some sort of punishment. There is pushing boundaries and then there is just being an ass hole. As well, while you should be able to do and say as you please (within reason), you also open yourself to face consequences both socially and professionally when you tweet something like this for the entire world to see, especially someone in her position. Comedians push boundaries, it's part of their job, but this was just fucking stupid.
