Just by garnering awards one doesn't garner love from the public. He is a spoilt person who has done more harm than good to the music industry.
As far as the "Baby" song is concerned, it is the perfect example of how fame is brought by infamy.
And, frankly speaking I don't hate him, he makes music and I cannot, in-fact nobody can, judge music. I just dislike his music.
People hate him for his behaviour and not his music.
