Please read the excerpt below. "I also belonged to an underground Boy Scout group, I was an avid underground Boy Scout. The reason I say underground because we couldn’t be legal Boy Scouts. The Boy Scout movement, which was based on brotherhood and equality of all, declared that Jews are not equal and therefore all Jewish Boy Scout organizations were disbanded and Jews were also thrown out of those Boy Scout groups that were not with some affiliated Jewish school or something."
