Muhammad's Cartoon

I am asking myself why publishing houses are publishing Muhammad's picture when publishers know well Muslim communities would react to that publication in a negative light? Or why are individuals who speak against Islam? I recently came to conclusion that it serves the war machine engine, it does not enrich freedom of speech or religious discussion. It is about dehumanizing one another so killing would be easy.
I believe in humanity, I love everybody as Jesus told me love one another.
