I think you're simply appealing to emotion here to justify an unjust ruling and an unjust law.
I think the person you're replying to has a point in saying that some laws in Europe are pretty ridiculous. However, the difference is that that's a local law in the UK and not one that affects the entirety of Europe. Nor is it a widespread law in other European countries.
And fwiw I do think Europe is oversensitive about Nazis-related stuff. But for good reasons.
