Reading Muman's post randomly made me think that since Judaism says that just converting to it won't make you a better person, "what Judaism is does not depend on the behavior of Jews" (Rabbi Mizrachi). It seems a bit unfair to say that just because they were killing Jews for 1000 years and used their religion to back it up, what the religion says is bad. I know what it's like though, and basically if you follow everything in Judaism, you know how to do everything in your life perfectly, and if you're a righteous Noahide, you aren't breaking any law that brings punishment, and you can choose to engage in whatever spirituality you want, and aren't necessarily paying anyone (though really you could do a cooperative equals type of church thing where you all own the building together and can invest in stuff and buy nice things for the building after if you want) and with Catholicism (because technically that's where it all came from, anyways) every different culture can have their different breed of it, because even though everyone admits it's a part two, it's not like you find many that are experts in it, or even a correct translation out of the tens of thousands of translations they put before part 2. The Filipinos or one of those guys can nail themselves to crosses and take stuff to foam at the like they used to, the Haitians can do Catholic mass with Mary and do voodoo like they used to, most everyone can have their mother, father and son statues like their ancestors most likely used to, the Greeks can have their strict religion like they're used to, the secular states all have varying degrees of watered down versions of it, (because didn't "G-d"'s avatar-son love everyone? If you follow the religion correctly, isn't the proper response to be loving?) and the Americans have their versions which are different from the British mostly, and the Chinese return of the messiah lady has a lot of Chinese ways mixed into her thing. Africa doesn't count because it's basically all missionaries from other places. But yeah, who can really follow 100% what the book you claim was also written by G-d, you're left with "be loving" for billions of questions that will require you to interpret that twice as many ways. You also have to tell people about the book, and love them while knowing that they will burn in hell for all eternity if they don't hear about a story, and really believe that it happened based on the testimony of the people in the book and/or either say or say and believe that G-d's son-avatar came into the heart that G-d made and controls every aspect of. You can be for or against the Jews, "Jesus was a Jew" doesn't indicate in itself that you should at all like Jews. To say you're Jewish or Catholic doesn't mean anything, but to say you're religious when you're Jewish always means a precise set of things (unless it's considered heretical or traitorous, like Neutered Kapo) and to say you're a religious Xtian doesn't mean anything other than a belief in a 15 second story. You can't compare apples and oranges that way. Judaism is a 100% perfect religion (and no Catholic denies that the Torah came from G-d on mount Sinai, though they say that G-d changed his mind about the way stuff should be done) and Catholicism, without mentioning premise validity, can be followed religiously and 90% differently from the guy down the road or your great great grandfather.
Muman, their nations are going to attack Israel and try to destroy it soon, and they even claim they believe it. There's nothing you can do to stop it, other than cause Israel and the nations to turn to G-d. Fighting for their support is like the Haredi fighting for support from the secular government in exchange for loyalty.
