Are nearly six hundred former Witnesses really that hungry for justification that they support gross behavior and misuse of funds?
You get weird psychology at play. People don't like to admit they have been duped, so when they are, they become even more ardent supporters.
Not like that weird group that thought the end-times were happening in 1914 and disbanded when they didn't. Oh, wait ...
There's a market for people who want to hear bad things said about the WTS. Just like those with TDS would tune and and whoop and holler at late night "comedians" who simply made insulting comments about Trump. Nothing clever. Nothing funny. But lots of people acting like it's the best thing ever broadcast.
