I don't think it's fair to judge a religion based on the actions of a few of its followers, whether those followers be jihadists or Crusaders. I DO think it's perfectly valid to judge a religion based on the actions of its founder, and it doesn't take a very long study of Christ or Muhammad to note some striking differences...
Muhammad's resume included murder, war, likely date-rape (if you can even call killing a woman's husband and marrying her the same day a "date")...
Christ? Well, he knocked over a table and pwned a fig tree.
Both of their followers have done horrible things over the years, but only one of the founders might be proud...
The big problem is here in the west, we don't burn or ban books. So you can get a more complete picture, if you're interested, and not just a church-approved story.
Even so, I've said it before and I'll say it again: the vast majority of Muslims are more than likely the same as the vast majority of Christians: followers by title only. Just think of how many "Christians" you see that consider Christmas the most important holiday.
