This kind of thing makes me cringe a little.
To me, people should be able to teach/preach whatever they believe within the walls of their own building (or rented stadium) without being confronted by those who disagree with them. Once they step out the door and start teaching/preaching in public places, at peoples doors or start asking people questions about their beliefs, they are fair game as far as opening themselves up to hearing opposing beliefs/opinions.
I understood what the guy in the video was talking about only because after being on this site, his alternate un JW like line of thinking on the matter of the memorial, is familiar to me . To the folks in the audience, their train of thought is elsewhere at the moment and this guy very likely confirmed all the paranoid ideas they have about those who are simply former JW's.
I've heard an older interview with the this guy some time ago and he seemed quite well spoken and balanced for the most part. He seems to have declined as far as being a stable person. What can you really tell from a short video but I was surprised how poorly he came across on this particular one. I guess the bottom line is that it bothers me that because I'm no longer a JW, this is what people think I've become a part of, especially when I've made sure to maintain my personal dignity whenever I've had dealings with them. (just my 2 cents)
