Two days ago, when Israel was still getting hit by hundreds of rockets from Gaza, and before the IDF began fighting back, before the targeted assassination of Hamas military leader, I was blocked on Twitter by someone whom I respected. Not unfollowed, blocked.

Why did she block me? Because I made a joke about the Right of Return in response to a post by a Palestinian friend of hers. The Palestinian didn’t block me, and in fact replied politely to my comment. It amazes me that I can have valuable discussions with Arabs on Twitter, but throw in one Israeli who is farther left than I am, and she blocks me. To the best of my knowledge, neither Arabs nor Israeli rightist, many of whom have ample reasons to block me, have done so.

Now, more than ever, communication channels must remain open, even if it’s only civilians tweeting their opinions. Engaging.
