Yes, I understand. I have heard that some thought that Lashon HaKodesh should not be used for anything but Torah, and secular language should be Yiddish... I didn't realize NK believed that too...
They twist things. Also those even claiming that Hebrew should be used only for Torah, I wonder what King Dawidh, the Prophets and the nation of Israel spoke in every day conversations and going to war or business when not learning Torah. Did they make some other language or did they just not speak/communicate since Evrit (Oops Lashon Hakodesh) should only be used for Toyyrah. The
REAL reason why they say not to speak Hebrew is because they are afraid that by educating and allowing its children and members to learn the language of the people all around (Hebrew in this case) would get them to communicate with the other Jews and get them to leave their cult-like existence where they are told what to do and think and what to believe and read. They might "assimilate" with the other Jews then.
