I wonder if persecuting isn't forbidden on Sabbath.
I may have misspoken here. But I don't think they are prevented on the Sabbath from discussing among themselves an agenda for the following week's program of persecution, or from reflecting upon the previous week's persecution activities. One of the reasons I referred bloggers to the link above was to rid any naive person(s) of the notion that the only thing which ultraorthodox Jєωs do publicly is to bob their heads up and down in front of the Wailing Wall, or amble along the thoroughfares with heads down and hands folded behind their backs.
Considering these missionaries are Protestant I don't have too much sympathy - the Protestant missionaries are like a cancer spreading into all the countries, even Catholic-only countries and leading away thousands of Catholics from the faith.
I do know that these Jєωs also persecute the minority Catholics in Israel.
Looking at it from the point of view of the Jєωs, however, I do understand why they are doing it. They are trying to protect their fellow Jєωs from being joining what they think is a false religion. Afterall, didn't the Church in Catholic countries try to prevent heretics from publicly preaching to the Catholics and that is why there was the Inquisition? These Jєωs are demonically inspired but, like Saul before his conversion, they do not realize it and think they are defending God.
