Well, some of the non-centralized social media is quite left-wing. If someone favours the SED or other parts of the ex-GDR regime (like FDGB etc) then it's IMHO already bordering on left extremisms. After all these guys enslaved a hughe population to make people do their biddings. If that is not extreme, I can't say.
That said, if you insisted that some "Germany's Independence Day" existed, then it's perhaps that what got you banned. Germany was never really a colony. Not of UK, not of Spain or Portugal, or not in newer times of Russia. Many countries that were a colony of them, or just annexxed, have an independence day. Germany doesn't --- the last time it was partially colonized, in roman times, there was no Germany.

Perhaps you mean the reunification day :-)
