Well for starters "behold, all things are become new" is Paul writing to the church in Corinth and he is talking about a new birth in Christ. So that specific biblical phrase holds no weight on this case.

2nd. I agree that media lies. However 2 things can be true, media lies, but they didn't lie about Hitler. For this to be an acceptable approach you have to accept the premise that Media today is not what it was before. Nevertheless, your argument about sources should hold weight to the products borne in the present. Take for example, neo Nazis as it exists today, they are bred by the writings and speeches of Hitler, all which are documented. Countless hours of speeches and writings from the man himself is what drives the small groups of neo-nazis to accept genocidal acts as a form of ethnic cleansing. So "by their fruits you shall know them".

3rd. There is no way in hell that all the logs kept for human experiments and all we know about operation paperclip is fake, so if you accept one, you have to consider accepting the the root cause and therefore the blowback we are suffering today. If Hitler was innocent, and CC and Human Experimentation did not occur, why would Op Paperclip would yield the problems we are suffering off today. You have to have dehumanizing acts in order to force or coerce humans into experimentation without their knowledge or consent.

Cheers.
