A Facebook page called The Zionion seems to see itself as some kind of anti-Israel Onion satirical site (update: the page seems to have now been taken down).
But when you peel away the top layer, what you get is antisemitism.
Case in point: This despicable post in the wake of the murder of four Jews in the Paris kosher supermarket.
This post was subsequently shared in another Facebook group called An Independent-Sovereign Palestine and Safe Israel (which despite its name is also used by some to spread hatred of Israel).
And a number of people, including the detestable Greta Berlin, showed their appreciation for the idea of murdered Jews.
This post was brought to you by the Department of Anti-Zionist-Not-Antisemite (hat tip: Adam).
