Well isn't that your own interpretation and personal opinion about Islam? You have your freedom of speech but your first ammendment right can not infringe upon mine in freely exercising my Constitutional right as an American.
I'm not infringing on any of your rights...even though your religion would infringe upon mine.
Which part? I'm giving you a historical interpretation based on biblical exegesis and my study of American History. You can't do the same with the Koran.
Personally...I think Mohammed was a filthy animal(rapist and pedophile) and Islam a filthy religion that is leading you straight to hell. You are very lucky to be able to worship in a free country.
By the way...how many Churches or Jewish Temples are there in Mecca or Medina?
