As a musician, one of the greatest disappointments to me was the conversion of Cat Stevens to islam. I grew up listening to his music. I found his voice and his lyrics tremeandously comforting. And then he gave it all up to join that hate filled religion, which espouses anti-Semitism, hatred of the west, hatred of women, hatred of gays, and which preaches a convert or kill approach.
I don't know if anyone else liked his music, but I did. I still listen to some of his early works on the computer and it reminds me what can happen when people choose the dark side.
Does anybody know of any other conversions like this, which they found disappointing?
