nothing more than a meaningless coincidence that the people attended some study centre. by the same token, they probably went to school - so maybe the education system is the real culprit.
could just as easily have been the JW's that were knocking on watso's door last sunday - watso told the head door knocker, that it was a lovely day, and maybe there were better things to do than go door knocking.. the head door knocker probably got upset, and thought that he would lop off a few heads on anzac day
