...that he wants the teachers to return to the root of education to help students grow up to be humane (people); that the efforts of the teachers should not help students to become a well-learned monster, or a versatile pervert, or a well-educated slaughterer...
Excuse me, OK? but pardon me...
Is this individual who claims has witnessed imaginary events trying to teach what?
Do you think that remembering past events will "teach" you to be "humane"?
Provide an example that remembering the forcing of thousands of American aborigines hundreds of miles walking thru desert areas to a Reservation in New Mexico, will "teach" you to become "humane".
I think that your main intention is not about teaching others to be humane but your topic is just another attempt to promote the propaganda that gas chambers existed in Nazi camps.
Please, after reading my reply, don't play of being the victim that I am a Holocaust denier and similar incongruousness.
The plain truth is that scientifically speaking, there is not a minimum possibility that those gas chambers ever existed in Nazi concentrations camps.
The plain truth is that no one learns to be "humane" by listening stories of imaginary atrocities, or even if the stories were real.
Being humane is learned thru good examples, like mercy on others, helping the one in need, working for the common good, etc.
If that dude has spent his life spreading lies about events that never happened, I can tell that such is the saddest and miserable life ever lived by someone.
Teachers must teach students about "compassion" on dudes like that WW2 survivor, who deserves being in a mental institution rather than promoting being humane thru the spreading on nonsense.
