Your post is quick to absolve Arabs.
The Pakis are muslims who are of similar ethnicity to the Indians who are mostly Hindus.
The Iranians are Persians, not Arabs.
The problem is Muslims.
I'm guessing a desire for basic factual applicability of comment to the article on hand has a lot to do with it.
Also, the fact that not all Arabs are tribal islamic bastards like these animals might have something to do with it. Maybe he just doesn't like Arab Christians being slandered as such.
