"So What if He's a Muslim?", are Obamites serious that they don't want to know or care about his background?

To me these are warning signs that something's not on the up and up. Most of these people here must not be old enough to remember much about 9/11 or they're wanting to be right about this so their taking a chance on him just to prove it. What if you're wrong? Should you take a chance on something as important as this? Do you think just because so many people are voting for him then it's ok? Think about how long the terrorist were in the U.S. during 9/11 and nobody knew what they were up to until it was too late. I could be wrong but I don't want to take that chance to find out.
