Sorry I am not aware about the Germany fake news, so link some reputable source to it, afaik Germany has very strong laws about fascism, nazis so make sure this is an EU problem and not Germany old laws unrelated to EU.
And I mean there are many stupid proposals, but there is no in effect law to put you in prison because you are supporting some legal political party that is in opposition. There are laws that you might be punished if you are doxing someone and calling people to kill that person online and this is not some law the EU created, it would be stupid to have a law to punish me if i call my neighbor werius stuff and damage his reputation but there would be no laws to call for killing of a specific person or a group of persons.
