His generation fought against a unified Europe...
That's one way of looking at those days. I think of fascists and ultra-nationalists seizing power throughout Europe, often through violent means, and seeking to subjugate or destroy others. I think of the explicit rejection of internationalism, and the identification of it with the Jewish people. I think of a time when people were dehumanized because of where they came from or who they were, and then exterminated because of it. I think of a time when people with opposing political views were murdered in cold blood.
Implicitly or explicitly equating the ideals of the European Union with those of Nazi Germany is one of the quickest ways to lose all of my respect. It is vile.
