Some week ago there was a poll with the result that more than 30 percent of the germans think it should be prohibited that supermarkets sell christmas-stuff before a deadline. Why the @#!! do they want to tell my merchant not to sell my beloved "Speculatius" in october?
Because whatever people don't like to see should be forbidden.
That's why:
Gay marriage should be forbidden. (eg. France)
Nudism should be forbidden. (eg. USA)
Kissing in public should be forbidden. (eg. Indonesia)
I don't really see anything special in Germans here. Whatever we don't like, whatever we feel uncomfortable with, we want it banned, locked up, hidden from our eyes. That's just the way we humans are

Ja, vielleicht ist das nur menschlich. Ich habe trotzdem das Gefühl, dass diese Neigung in Deutschland besonders ausgeprägt ist. Aber vielleicht ist das auch nur Einbildung. Bekanntlich sind die Wiesen wo anders immer grüner
