So he tries to prove that we are living in the last days without any evidence, but instead a series of unsubstantiated assertions ("never has there been a time with so much lack love and affection"). And uses things that are not even part of the so-called "sign" (abortions, pollution). Then proceeds to ridicule the "ridiculers," stereotype them, and declare they are only fit for destruction!
Instead of addressing the most glaringly obvious reason people don't believe we're living in the last days, i.e, the complete lack of any solid evidence, he goes on to give his own reasons:
1. They are blinded by Satan. (If that is so is it really their fault? Why should they be deserving of destruction? If they've been misled by a more powerful being that does not make them wicked... it puts responsibility on God, if he truly wishes for all to be saved, to "unblind" them).
2. They are victims of "gradualism." Pulling out that old frog illustration like its the first time anyone's heard of it. Implying that people have not made a proper investigation of the facts or history, when the opposite is more likely to be the case. Most people have come to the conclusion that we are not living in the last days because they have made a more thorough investigation of the historical evidence instead of just accepting Watchtower assertions or misleading twisting of statistics.
3. They are haughty, depraved, wicked. His final brilliant argument is to imply that if people have allowed themselves to fall prey to his first two points they must be morally corrupt - the are deserving of destruction and good riddance to them! Or "so be it" in his words.
So in summary, what I got from the video was this: if people are too blind or stupid to see that we are living in the last days, and they have allowed Satan to blind them to the (non-existent) evidence then Psa 92:7 applies to them: They are wicked ones sprouting like weeds and their only reason for existence or worth as humans is to be annihilated.
Nice demonising and hate speech that towards those who don't accept your opinions. The JW leadership are not extremists at all, such tolerant, peace-loving people!
