It seems like left wing riots are much more common than right wing riots (in Europe and America) and those seem to draw the most attention from governments.
However, the reality is more complicated. Esp. in America, there are a ton of recent examples (2016 to present) of mayors / college admins telling police to stand down / avoid protecting right wingers from left wing violence. Plenty of Trump supporters have been punched (or worse) during rallies. People openly call for punching Nazis (which seems to be a blanket term for individuals for conservative sympathies).
Berkley? Evergreen? San Jose? The stand down orders are tantamount to a conspiracy to deprive right wing people of their civil rights and that's de jure discrimination if not active de facto discrimination.
It's tough because both sides can point to some injustice and correctly say that there's an element of ideological discrimination at-play. It's disappointing that calls to reduce political violence are equivocated with partisan positions.
I can assure you that if you create a right wing website with bomb making instructions and a call to action to destroy the government, then it too will be shut down.
This isn't about left vs. right, this is about order vs. anarchy.
That is of course one instance, but if this is the first time a left-wing website has been shut down by the German government, it looks like it's no worse than 1:1!
