Okay, so they're going to block his view. Well he may be able to block their hearing the meetings with broadcasting over loudspeakers about WT indiscretions proving the GB to be the bunch of liars they are and have been through the decades.
Get some noise cancelling earphones for yourself and then let the show begin. Every morning meet them for field service. They'll quickly change to a home location to meet for service. Every Sunday and Weekday meeting let the show begin in earnest. If it was good enough for Drunk Rutherford to put his talks on loudspeakers and blast them from moving vehicles then it should be good enough for the KH attendees.
He could also play all kinds of Christian Church music, Mariachi band tunes, Saturday Night Fever Disco, or maybe AC/CD and Metallica if he liked instead, then again repeating the same Umpa band German beer drinking song might be just the thing to break the concentration of many in the KH and counteract the brainwashing spiel from the podium.
They say having a purpose in life can make you live longer and enjoy life more.
Well then let the loud broadcasting with a purpose begin!
Help undo the brainwashing going on nextdoor.
