While the vast majority of the comments online slammed the pop star, some people expressed support for him.
Heather Mirman cited a line from Anne Frank's diary: "Despite everything, I believe people are really good at heart."
"I think before everyone goes bashing Justin Bieber we should take a moment to think about these words and why Anne said them," she wrote. " ... He is trying to say that he would've been proud to (have) had her as a fan because of her courage and the fact that she believed in good."
Frank was 13 when she and her family began hiding in a dark and damp "secret annex" of the house to escape the German roundup of Jews in Holland in July 1942. She never left the house for two years, spending much of her time writing in her diary, until she and her family were found and arrested by Nazis in August 1944.
Anne Frank died of typhus in the Bergen-Belsen concentration camp in March 1945. Her diary survived to tell her tragic and inspiring story.
