She's an artist who put her work into the public domain. The standards for art and theater critics in New York are pretty rough. So, if people are telling her in colorful terms that they don't like her work, she should just get out of the kitchen if she can't take the heat. I mean, really, some of the critics who write for the New York papers are brutal. In addition, she brought a lot of this on herself by saying Brady was paying attention to his cell phone (which I don't think he could have had in the courtroom anyway).
If people are threatening her or writing obscenities to her, that's another matter and she should not have to tolerate that.
But telling someone that you think your three year old could do a better job is not "cyberbullying." By the standards of NY critics, it's actually a mild criticism.
For the record, I originally didn't like her drawings, but, as I look at them, I actually think she captures the mood Brady was in yesterday. Angry. Somber. That's certainly what I felt in the few seconds that I saw him up close as he was getting into his vehicle. By all reports his demeanor in the courtroom was, I should be with my teammates getting ready for a game, not here arguing about some made-up nonsense. On looking at those pictures, I think she captures that.
