I don't know if these people were missionaries or not, but Me'ah She`arim is not a tourist attraction. I'm a Noachide and I've been to Israel, but I don't think I'd have had the courage to try to go there. These are very withdrawn, insular people and are probably suspicious of anyone not identifiably one of them (surely despised white Protestant Fundamentalists can relate to people who feel so under siege from everyone else that they lash out at all outsiders). Too bad, since these are the people who are best equipped to teach the nations. Unfortunately an anti-proselytary position commits one to defense rather than offense.
Whether or not these chr*stian were "pro-Israel," there is something strangely apropos about the image of pro-Israel chr*stians being attacked by Jews, since it is always the pro-Israel ones who arouse the most Jewish fury. I doubt hear of "ultra-Orthodox" attacking Catholics or Armenians or Eastern Orthodox. But then, Catholics, Eastern Orthodox, and Armenians never proselytize. Some people seem to consider a non-proselytary position as the be-all and end-all of everything (not only Orthodox Jews, but Catholic and Orthodox chr*stians whose guts churn at the very thought of a Protestant missionary).
Those chr*stians who are condemning this "attack" need to realize that the Orthodox Jews they love so much regard chr*stianity as a false religion and don't want to be asked to convert. But these are the same people who are on your side when it comes to homosexuality, Darwinism, etc. If you cheer them when they "attack" homos, don't condemn them for attacking other "heretics."
The announcer who used this incident as an excuse to accuse pro-Israel chr*stians of "hatred" is an a-hole. Fundamentalist Protestants think they have to convert everyone. They don't even baptize their children, but wait until they reach the "age of reason" and "convert" them! Do they hate their children? Of course not! It's not that pro-Israel chr*stians don't love the Jews; they simply believe a false religion. If they were converted they would demonstrate their love of Jews in a more appropriate way. Wonder what this announcer thinks of non-proselytary Orthodox chr*stians who hate Israel's guts or the non-proselytary Vatican trying to get its mits on Jerusalem?
Finally, this whole thing--pitch the fundie Prots and the "Jewish mullahs" against each other--is just too darn convenient for certain people who dislike both. There may be much more going on here than meets the eye.
I wish that I had more time tonight.
There are portions of your post that are also likely pretty offensive to some.
Christians who don't baptize their children?
I know that you won't try, that is good, because you can't produce any verse in the Bible (OT or NT) that even remotely suggests the baptizing of children as an imperative.
