He said that some say the Jerusalem fell in 586 instead of 607. But then you would not get to 1914 but 1934 and nothing special happened then.
This is what kills me and what proves that their "research" is not done with an open mind, but with a preconceived idea. "Nothing special happened" in 1934, therefore, every reputable scholar, historian and the bible itself must be wrong, because it doesn't jive with our doctrine that Jesus returned invisibly in 1914. Makes perfect sense.
The other point he tried to make was that WW I was proof of the 1914 date calculation quoting some historians who said that it was a turning point in history.
Big deal. There have been many other "turning points" in history. That doesn't mean anything.
The WT study afterwards had a paragraph about apostates. So one sister gave an answer that some apostates fiddle with the date calculation for 1914 and we should not listen to them.
Well golly gee......how does this sister know that 'apostates' fiddle with this date if she hasn't been researching it or been told herself? If Jerusalem was destroyed in 607 BCE, she, and every other Witness should be able to defend it without any problem whatsoever.
