Is it true that Germans were doing an anti-Muslim march?
Are they going Fourth Reich on us?
Yes to the first question, hopefully no to the second.
There is this thing called "Pegida" over here, which stands for "Patriotische Europär gegen die Islamisierung des Abendlandes" ("Patriotic Europeans Against the Islamisation of the Occident"). Their behaviour is somewhere between deeply concerning and ridiculous.
A couple of Ossis, nothing big, really.
Yeah, because that's something that's totally only happening in the former GDR and not all over Europe, so there's actually not a real problem. How convenient to have a former dictatorship at hand which helps explaining away all social unrest!
Otherwise, I cannot agree. In the U.S., employers will fire you, you might be placed on "potential domestic terrorist" watchlists, marked for harassment and denial of access to rights by authorities, and even targeted for assassination (Link: The FBI was aware of an assassination plot targeting Occupy organizers. Didn't bother to warn the targets, and still refuses to release any further details beyond the FOIA revelations that there was one and they knew about it.)
Freedom of expression is not so respected in the U.S. as it's supposed to be, and can be a serious danger to livelihoods. Removing the ability to do so anonymously is a really easy way to discourage many from doing so at all.
Wearing baclavas/burkas/whatever is not the appropriate way to stop such things from happening: Being put on any list requires them to have your name, which kinda implies you already were stopped by an officer and had your personal info noted
Which can be done for all kinds of reasons.
In Neuruppin there was a counter demonstration against Nazis in… I'd have to ask my mother or one of my brothers when that was. The police made three warnings (as required) against a sit-in. My mother and brothers tried to get out after the second warning, but weren't allowed to leave. Because they still didn't leave after the third warning (which they couldn't do) they were registered. The whole thing might have been a huge scandal afterwards, but that doesn't change that their names were registered.
Fortunately they aren't really politically active. For someone who is, this would have been a huge problem.
I think you underestimate the length our state goes to to make life hard for people who are politically active, even when they make absolutely sure to stick closer to the law than most people (because most people don't even know what they might be doing wrong).
