Why does Lady Gaga get more hate than any other female pop artist?

I personally like her music but I understand everyone has different taste so that's really aside from the point. But it seems like Lady Gaga gets so much hate and I really don't understand how she is any worse than Katy Perry, Ke$ha, Rihanna, or Beyonce. Unlike the previous names mentioned, she does actually write and produce her music, whether you like her music or not. A lot of other pop artists have been accused of plagiarism and people don't seem to care as much, for example The Black Eyed peas were sued four times for plagiarism. What someone wears and music videos don't really matter to me. So why does she get more hate than other pop artists?
