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.
It smacks way too much of blaming members of a group for the bad actions of their group long in the past. If we carry this to its (il)logical conclusion, those who blame the Jews of today for killing Christ are correct.
It also means that even if they cease their aggressive activities today we'll keep brining up those of the past, which reduced their incentive to stop being aggressive.
We need a statute of limitations on racial/ethnic/religious blame. I propose the point when nobody in either group remains alive.
