It is so absurd that they are so clueless about their religion and its history, teachings, etc...back in the 60's thru at least late 80's you had to know your stuff.
As for door knockers...I haven't seen them in this neighborhood for probably three or four years....never see them out on city streets ever either. Do they even do house to house anymore? Seems like it is no longer the thing.....that man with the writers inkhorn must be very bored with no foreheads to mark.
