Natrunia (Satmar) is legitimate and does indeed educate regarding anti-Zionism. Zionism is dead, and today’s post-Zionism is a real danger to Jews and Judaism, not that secular Zionism was much better.
The wannabe NK clowns hang around with our worst enemies, and in London one of them appeared as a witness for the defense in a case against an Islamic terror imam. Usually they endanger no one because even the yishmoelim don’t take them seriously anymore, but that one should have been put in cherem (he has a very generic first and last name so I’m not going to post it as confusion could result and harm could be done to an innocent man with the same first and last name).
The extreme NK spreads stories about having helped Jews in Iran etc as a way of legitimizing themselves. Those stories are urban legend. They could not even get the wife and children of the lunatic meshummad Youssef Khattab out of an Arab village.
The bloodthirsty yishmoeli vilde chayes in EY do not care one bit. They planted at least one bomb in Mea Shearim that was publicized. To them a Jew is a Jew.
