you probably have no clue to what this guy has written and so you think its about freedom of speech. But nothing could be farther from the truth. Chomsky advocates violence against Israel which he call aparthid. He calls for the destruction of Israel. So this is not free speech but whether Israel should give him a platform to advocate his hateful positions and thereby incite violence agast israelis. So why should they let him in. No counrty is obligated to give freedom of speech or entry to anyone advocating its destruction. No muslim country would. Did you see any pro israel speakers invited to Gaza or the West Bank. Any moron could figure this out.
