No, it's not a valid reason to dismiss anyone. Sinead O'Connor has been committed to psychiatric facilities, and has threatened suicide a number of times. She needs help and is clearly mentally ill. It is nothing to be ashamed of, I was just stating facts. If I offended you, I apologize. She hasn't had an album in many years. She isn't really on the radar of artists in 2016.
He's ridiculous and spews sh*t. He doesn't think anything he says is wrong when he says racist and sexist things almost every day. His performance on SNL was a blinding screen that made me dizzy and a terrible performances where no one knew where to stand. His fashion line is laughable, and half the models were in dyed American Apparel garments. Enjoy him on TIDAL ONLY (proves hos obnoxious he is), most people are through with his nonsense as you can see with the thousands of articles about his recent behavior. Artless hack.
