Ah, so Bieber is a "big no" because of his behavior, not his music. But I am just considering his music. I like it. And I still wonder if you have heard his best work, like "Pray." It is quite sensitive, and excellent musically, and it mirrors his genuine interest in people in need.
Remember too that his behavior was a phase that lasted for a year or so. Before that, he was hailed as a good boy, and (falsely) knocked because he was a girly boy. Now, he is more macho. He wanted to prove his "street cred." He is also upfront about his past mistakes, and he isn't making them now. All along, he has done a lot of good too, and no-one should knock his generosity and promotion of good causes. And his misbehavior is frequently exaggerated. He did not test as drunk in that incident in Florida, and he did it at night with his friends blocking off the streets, and going fast only in areas where there were no cars. He had the money to do it, so he wanted to drive a big fancy car.
Much too much is made of the Anne Frank incident. Maybe it was not the most appropriate thing to say, that she might have been a belieber. But after all, he was right, and it's also kind of charming to think that she might have been a Bieber fan if she had been a young girl in 2012. And, is that really such an insult for him to say? You can say it was "all about him, not Anne." He was "arrogant," OK. Full of himself. But you
can't say that he insulted Anne.
I really like this one:
