"he believes that ALL religious people are against abortion. ALL religious people are against stem cell research. ALL religious people are against science."

I can assure you that Cenk does not actually hold these opinions. What he means to say is that ALL the people who oppose those things do so for religious reasons. These political fights are always waged against the religious. People are so accustomed to the taboo against criticizing religion that whenever anyone crosses it they over-react.

No matter how much religious liberals distance themselves from the religious right, they seem to always take offense when non-religious people criticize them. As if to say, "Yes, we can criticize them, but just stand back there nonbeliever, you're out of line!"

One thing I admire about the fundies is that they stay true to their faith. They own it, unlike the modern religionists who play shell-games and do a tap-dance when talking about faith.
