That is good news!
I believe that Randy is unbiased. Ellen is just there, so no complaints. But I would not even give the benefit of the doubt to Simon or Kara. What judges say does matter. It shapes public opinion. A lot of people who watch the show give weight to what the judges say. The next morning Entertaiment section of news outlets on the internet splash the judges' comments as headlines. That shapes public opinion too. Simon's "giving birth" comment was completely rude and insulting even for Simon's standards. That may have been the last straw that did Siobhan in (Ryan probably thought so too, hence he wanted Siobhan to part amicably with Simon). Not to mention calling a man "girly" is the ultimate all-powerful insult one can throw at a man. Simon has graduated from the "irrelevant", "karaoke", "cruise ship singer", "all over the place" kind of comments to borderline personal insults.
Not everybody is made the same. Not everybody reacts the same when faced with the same situation. Tim Urban just laughed in the face of criticism. That was his defence mechanism. Crystal will pooh-pooh criticism. She knows herself too well. Mike does not like criticism. But Siobhan let the criticism get to her. I think her spirit was broken to some extent. Yes, she is an adult, but barely. I bet Aaron will

on stage if faced with harsh criticism that Tim and Siobhan faced.
Yes, in the end Siobhan decided her songs and her fate, but I am just trying to factor in the things that went into her decision-making. I think she did listen to the judges. For example, she did do the screaming in the middle of a song after Simon told her to do so. She was still criticized and then she did a very low range mellow song sitting on a stool.
Thank you!
