Most Germans today were not even born yet at the time of the Holocaust. I don't know your age but it makes me sad that you say, "we germans have cut off" rather than "Germans cut off ..."
I am 41, so I have definitely no personal responsability whatsoever.
But I am a German, so this is also part of my history.
It would be renunciation to blend out this subject.
Someone said: You bear no guilt, but you can feel ashamed.
Also, as the Nazis claimed to be the true patriotic germans (and neo-nazis still do so here), I refuse that by accepting what was and that is was a grotesque monstrosity and in no way good. That "those" define what is german can not be accepted, but for doing so, I have to accept what was.
So as I embrace everything what is good in our past, I accept what was not. Everything else would be renunciation.
