No, there isn’t. They just want to blame the left for centrism failing. Arabs and anti-war sentiment are convenient and evergreen “bad guys” in centrist politics and one that has been actively reinforced by the media since the genocide began. It’s a convenient scapegoat for an across the board failure of a centrist campaign.

And if this was actually the linchpin, then it wasn’t exactly a big surprise. The whole movement was trying to raise the issue and was repeatedly ignored.
