Hate and violence never helped solving any problem of mankind, in fact they made them worse.
As long as people are too under-educated to grasp this, they will always shift their focus from finding solutions to finding someone to blame for the problems they should better solve.
Violence has solved more problems than anything else in history. For example: Every defensive war ever. Or would you have preferred to simply surrender to the germans back in the war? Because that was always an option, as one of our leaders of the time reminded us.
Hold on right there.
You know, i'm from a country where the political leader of the germans (you know who i mean) surprise visited the chancellor and basically said "the troops are at the border. surrender and join the german reich or let many of your people die, you have xy hours to think about it, and you can also flee the country...".
And he surrendered.
This has a background, starting before WW1, out of scope now.
What i'm trying to say, "i" would not have had an option to fight the germs, because my own people would have killed me trying. I could have just gone to the underground, becoming a kind of unknown hero, dying in the process of sabotaging the militarian infrastructure.
After the war was over, we were "liberated" by the allies, getting occupied for less than 10 years, until we could declare the sovereign state again.
So your particular question doesn't apply to me, imho.
Still, WW2 only produced victims in the first place, on both sides (on all of "sides", to be fair). That's what i meant originally. Hate has started the thing, and hate kept it going until the reich fell apart. Even a defensive war started by offensive actions, and that's always the beginning.
