Sadly we don't know what "Josh" said. But by Bills choice of words "Maybe you should think about it too." it seems that he was talking about someone we knows who committed or attempted suicide. Or even possibly telling Keller to kill himself. Now none of that can be proven. It may never be. No matter what was said for the man who dedicated an entire show to suicide prevention (Link here to the playlist of those videos) it is wrong to tell someone to kill themselves. Hell, it's wrong to tell anyone this. It seems that even Keller noticed this and soon after uploading his archived version of the show to YouTube he later deleted it. Thankfully for us however someone saved the parts where things got a little messy for Keller.
According to the video of this, an estimated five minutes passed before someone called to confront Bill on his statements. "No. . .no didn't say that at all. Didn't say that at all. You need to get your ears together, Bud." was his response. He also added the wonderful little line "it's a sin to kill yourself." which he said multiple times in his previous show about the topic.
I hope Josh was a fake. I hope that this insane mans disgusting words didn't affect someones life in such a negative manner. For the second caller Bill, is real because I want there to be people not afraid to stand up to someone like Keller. Live and in action. If he's real he didn't waste much time to call and that's wonderful to me. Either way I'm looking forward to Keller making another excuse for what he said. I also am looking forward to him trying to get the evidence erased.
