UPDATE 9/30/2012:Geert Wilders just tweeted my Mohammad drawing to the left, which was actually inspired by a talk of his, "Time To Unmask Mohammad". More on that below, from April 3, 2011. "The historical Muhammad was the savage leader of a gang of robbers from Medina. Without scruples they looted, raped and murdered. The sources describe orgies of savagery where hundreds of people’s throats were cut, hands and feet chopped off, eyes cut out, entire tribes massacred. An example is the extinction of the jewish Kurayza tribe in Medina in 627. One of those who chopped off their heads was Muhammad. The women and children were sold as slaves. Confronted with the lunacy of Islamic terrorists today, it is not hard to find out where the lunacy comes from." - Geert Wilders from his op-ed, "Time To Unmask Mohammad"
As to why I give Mohammad a Hitler mustache - Growing up among Muslims, it was not uncommon to hear Hitler being spoken of in glowing terms. No doubt because of the hardcore anti-semitism inherent in both Islam and Nazism, and so within Mohammad and Hitler. And so it's natural that Mein Kampf - My Struggle - and with jihad literally meaning struggle, "My Jihad"- would be a best seller today in the Muslim world. Further, Hitler praised Islam as a "Masculine religion", emphasizing the hardcore misogynism within Islam. Hitler has been the icon of evil for as long as I can remember, and it's time Mohammad is made to be understood in that way as well. I refer to the Muslim World as A World Where The Bad Guy Won, regardless of the technically non-violent nature of many Muslims. As I put it recently -
Jihadists don't represent most Muslims. They represent Islam.
I concede the point that it is indeed an interpretation of Islam that is the problem. Mohammad's interpretation.
Back to the drawing at hand: I made Mohammad jaundiced, lit. & fig., to emphasize how sick and hostile he was. And Mohammad dyed his hair with the red dye henna, so I gave him a blood-drenched beard, also to emphasize how much blood has been spilled in the name of "peace".
Oh, and one more thing, Islam meant peace before Mohammad cartoons. :)
