When Israel haters need to find an easy "proof" that Jews and Zionists are racists, they go to Facebook or YouTube or any other uncensored comment forum and find some convenient anti-Arab or anti-Muslim bigot to quote. It is a lazy way to pretend to make a point, because every group has some idiots so the existence of idiots is used to generalize about the entire group. They ignore the denunciations of the bigots on those same forums, because that would ruin their thesis.
Of course, these "progressives" are engaging in stereotyping, and obvious dishonesty, which is a major crime when anyone else does it, but that doesn't matter to them. They pretend they are revealing a "higher truth," which is pretty much how they justify their own bigotry.
But in the aftermath of this morning's terror attack, and most* others, there is something striking about the Arab comments on various venues.
They are unanimously supportive of killing Israeli civilians.
I cannot find a single naysayer, a single person who says that killing a father of five standing at a bus stop is wrong. On the contrary, they will often try to justify it as a "right" or as if it is an obligation under international law.
Hundreds of Palestinians on the Fatah Facebook page are cheering the attack. (Palestinian Media Watch has more.) Every single person who identifies as "Palestinian" on Ma'an's English comment page is equally happy. (The official PA Wafa news agency reports the incident as the police shooting and wounding a Palestinian Arab around the same time that a "settler" was stabbed to death.)
Finding idiots on message boards where thousands of people gather is easy. But finding an Arab who is willing, on his own, to publicly condemn murdering a Jewish civilian is well-nigh impossible.
That is a real story that can be gathered from reading message boards and Facebook. And it is a story that Western media will not touch with a ten foot pole.
There is one exception I am aware of - the murder of the Fogel family in Itamar. While plenty of people praised the murderers as heroes, that was the one time I saw pushback on Arabic-language forums, since stabbing a baby was too much even for them.
