There are many reasons people may be barred from entering the state of Israel. If they present a risk of criminal or terrorist activity, for instance. If they tell lies at the border or don’t cooperate with border officials. If they’re suspected of trying to immigrate illegally.
But now Israel has added a new rule — to implement a noxious law passed by the Knesset in March — requiring border authorities to refuse entry also to people who have publicly supported a boycott of the country. These visitors would be turned away not because they are suspected of a crime or pose a security risk, but because they have expressed an opinion in favor of a nonviolent protest movement that is unpopular in the country.
