So people or governments are not allowed to make mistakes and learn from them? If, apparently, something likewise happened in the past and caused lots of problems, the German government should just let it happen now just so that it isn't 'ironic'?
Not to mention the fact that the German government around the second world war was completely different from the current German government in terms of the actual people making it up.
Is it 'ironic' when governments try to improve equal rights for men and women just because there is oppression of either of the two in their past? What nonsense.
