The hubbub over that Facebook page resulted in its removal... and subsequent replacement with numerous duplicate pages. Unfortunately, despite the original page's disappearance, the promised widespread Muslim boycott of Facebook never materialized. With that said, if they failed to follow up on one action endorsed by the group, can they be expected to follow up on any other action?
Or did the ones who stayed behind merely become takfiri apostates?
Debating whether Facebook should be the means by which such activity is coordinated is futile, as there are already numerous "I hate <whatever>" pages floating around on Facebook, as well as Arabic-language jihadi websites and "Inspire" magazine. The real question is how to get rid of the hatred at its source, or at least isolate it permanently. There are numerous threads and published opinions on this website and elsewhere addressing this matter.
