Im German, so let me declare the situation.
FIRST of all:
PLEASE dont say such things like: "They [Germans] have the most violent past in history!"
Thats right on the one hand. Yes, the past was cruel, and what THEY did, the people who lived in this time and made this cruel things happen, wasnt right.
BUT the most peoble living today are not spoiled by the National Socialism. Yes there is a National Socialist Party. And there are people electing them. But we try to ban those Parties, but we a frightened they go underground, and then they wouldnt be under control.
But I give you my Word that 99 Percent of the German people are not National Socialists.
And I am also sure that also in the USA ore GB are National Socialists.
But...back to topic:
First there were in 2002, 2006 and 2009 young men and pupils which ran amok. Some our politician think that violent computer games are the reason why this people did that.
In Germany we have one of the most rigorous law for the protection of children and youth. But they think that they have to control everything and everyone. They started to censor the internet!
