"The point of the statement is to imply that Muslims are somehow inferior to the other group, so yes, it can be perceived as racist whether it is "true" or not."
I disagree, bo_sox, as to the implication--
The implication isn't that Muslims are inferior...
But rather that religious fanaticism/states endorsing that fanaticism has led to an entire people falling behind in terms of the Nobel Prize race, not to mention science and literature.
And...he's right.
The fact IS true...
And, well...
When a book ("The Satanic Verses") which was intended to be SYMPATHETIC to Muslims generates a 20-year-long fatwah and ruins that author's life for the mere crime of writing a work of fiction...well, that's religion ruining a culture's capacity to have full creative and intellectual freedom.
"Why not mention Christianity and Judaism?"
1. The same reason take more issue with Islam on an international level--it's not the Christians and Jews (currently) who are blowing up buildings and people in the name of establishing a new Caliphate because of their own holy book. That doesn't make their holy book BETTER...but they're just (mostly) not the #1 threat to peace.
2. There are so many Jews in the various scientific fields, and have been for centuries, that really, I think (most) Jews are past that...the oldest of the three, arguably it's the furthest along of the three in terms of integrating into a secular world.
3. I think most Christians realize that, first, science and advancement is helpful, and with the exception of those trying to teach Creationism or Intelligent Design, are letting science and literary/freedom of expression proceed.
So it's not that Muslims are somehow inferior...
It's that Islam, as practiced in many parts of the world right now, is holding an entire people back...when you refuse to acknowledge evolution and threaten to kill an author for the terrible crime of writing a novel, that's not progress, that's a definite problem.
