There's little to be gained by trying to reason with Marx. Lately, I've been finding his posts quite amusing because he seems to embody all the usual hasbara techniques in all of his posts. 

Deflection, false equivalences, accusations of anti-Semitism and supporting terrorism, blah blah blah... not one whit which justifies what Israel is doing to Palestinians.

It's almost quaint, except it sounds like a broken toy after a while.
