Ok but based on all you said it doesn't make sense to still call him a satmar just because he's from a satmar family. Seems he does not follow the satmar customs and is more like a satmar turned muslim who attends Chabad.
boy that is something. "satmar turned muslim who attends chabad".
Anyway I think he's some deranged Muzzie or Muzzie wanna be based on his groups (learn islam etc.), some dress pictures (with the Muslim terrorist Kafiya and not 1 with a streimel) and that poster that doesn't even say or blame "Zionist" but straight to "Jews" .
+ I just saw, he doesn't even have a Kippa on in some of his pictures. He either has a hat, the muslim Kafiyya or nothing on at all.
Apparently he wears the Kefiya " Avi Ibrahim Balser I wear it on Purim and on May 15, to show solidarity. " (May 15 being "nakba" day. )
Overall YIMAH SHEMO to this animal no matter what or who he is.
