I did my first 17 years in a camp, and yes it was cold all the time, and yes I had medical experiments, and psychological torture all the way. I survive.
So your 6 years of nazis camps, at most, are really not weighty enough to what I know about human shit, and pretend you can do worst to children because of that. Think the fritzl case, but from 0 to 18 years old, you’ll get an idea, little genocide religious delirious people crying for money.
Anyhow. At least we all end and die. For good?
