Accusing the Witnesses of targeting society's weaker elements, including new immigrants, the poor and the handicapped, critics blast what they call the group's devious recruitment methods. "They've mapped out all of Israeli society and then target segments that don't get attention elsewhere," said Cohen. "They introduce themselves, they smile, they are nice and they are successful. They cynically abuse people in distress and like other cults in Israel are growing." Cohen asserted they've actively proselytized in group homes for the deaf-mute, adding, "Jehovah's Witnesses, messianic Jews, scientologists all thrive here because there is no public awareness to counter them."
"They target the less educated people and not the university professors," said Ruth Cohen, a former member who returned to Judaism in 2002. "In Tel Aviv, they go building to building, but in Jerusalem, they are more careful because they are terrified of the ultra-Orthodox. They target Russians, foreign workers and Arabs - but not Muslims, because that is considered too dangerous."
Claiming to have nearly 7,000,000 practicing members, they are especially controversial for the way they treat those who leave the flock. A Jehovah's Witness who behaves in a way that the community deems immoral is completely excommunicated, or "disfellowshipped," in the parlance of the congregation - an experience Ruth Cohen had to live through.
Jehovah's Witnesses do not consider themselves part of Christianity - which they see as idolatrous - despite their belief in Jesus as the messiah.
