Some folks will never get past the moral sheep herding to dig to deeper truths. It's really difficult to challenge one's own belief system that's been conditioned into you for your whole life. 2016 has been a re-revelation for me in that respect as I hadn't realised how fast asleep I was.
The "holocost denial" phenomenon does not benefit those that would subscribe to such a view. So surely the logic would be to look to those who would benefit? The obsession with looking at national states for answers is also a mistake I feel. They are merely conduits for power grabs from more powerful forces. I might further suggest that laying blame on any religious group might also be a misstep.
If anyone on this thread is interested in a deeper dig I would thoroughly recommend Carol Quigely's Tradgedy and Hope which is a manuscript with research mined from CFR sources etc. I've only just discovered this but it's blown my tiny mind. It's a tough read as Quigely was a military man and not a writer, but I haven't yet come across a more enlightening mine into modern global history as this. Quigley was also acknowledged by Bill Clinton to be his chief mentor (but don't let that put you off!) A very important and telling note on this text is that Quigley confided with friends that he dare not overly cite certain banking families in this book as he was convinced he would be killed and his work suppressed.
Here it is for free. You can probably download to a smartphone and read like a kindle...

For some reason it went out of print for years until 2014
