I have family that suffered at the hands of communists. Many were deported and exiled, some were sent to gulags. Some of them made it back, some died there, because the conditions in Siberia were horrible. Do you think it would be reasonable to start fining or jailing people who make jokes about "being sent to the gulag"?

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.
