The actions taken by Arabs and Muslims described here were spread out over 1200 years. Talking about all of them together without mentioning that rather relevant fact seriously weakens the logic of his case.
The fact that it has gone on for 1200 years makes it better in your opinion?
To me that means there is an unremitting pattern of persecution entrenched in the culture of these Muslim inhabitants of the Arabian Peninsula. What they did 1200 years ago they still do and want to continue to do, unlike other civilizations, like the West, which have evolved.
