Those who view all Muslims as potential terrorists or as individuals who would be supportive of strict Sharia Law are racists and bigots. Yes.

Racism is assuming that someone's race determines their worth or behavior (statements along the lines of "All Muslims believe dangerous violent things"). Bigotry is the intolerance of views that are not your own, which there are plenty of comments here about how Sharia law is fundamentally anti Christian and anti-American. The argument is not if or if not that is true in some cases. I agree that there obviously are cases where it is. But when members of our own community are assumed to be associated with those things, or are assumed to be complicit with those things that is a bigoted view of Islam. The inability to see the differences between Muslims can be racist and bigoted. It doesn't matter if it's rooted in a moral opposition to clearly abhorrent things.
