However, people are not saying on the day they are born that they will be terrorists, rapists, killers, etc. It's the ENVIRONMENT they are raised in, not the way they are born.
To say not everyone is good inside is basically saying people are either born bad or born good and nothing can be done about it. Everybody is in fact good inside, so I find no offense in the song itself, but rather the negative reaction it is receiving from fans.
What if the song was about everybody being bad inside? Because we're all mortal beings, we all have bad in us as well. People would have a fit hearing a song like that, though. Why is there a double-standard going on?
