This is not a restriction of Free Speech. Germans know the problem Americans refuse to acknowledge.
Hate Speech's only purpose is to incite violence, get people killed and destroy families.
Confusing Free Speech with Hate Speech is an American problem. While its recognized for what it is internationally there is nothing preventing it in America.
The message is clear in America. You can do say and do whatever you want under the guise of Free Speech, just let the Police take care of the fallout.
Based Stickman is the embodiment of this problem.
The violence will continue and the divide between Americans will widen as long as America continues to support Hate Speech.
There is no amount of diversity that can change this.
