Beware the Ides of May.
This link will take you to a Facebook page that has been set up to encourage a third intifada. It encourages Muslims everywhere -- not just Palestinians -- to converge on Israel on May 15. It does not explicitly state what they should do when they get here, but the logo and the use of the term "intifada" are not encouraging.
Last time I checked, the page had been "liked" 328,587 times.
When you click on the link, you'll see a "Report Page" button on the lower left. I encourage you, if you are so inclined, to report the page as containing hate speech.
