We are to stifle free speech because of "human dignity"? That's what dictators say. That's what extremists say. Theo Van Gogh was stabbed to death over a short film that insulted the "dignity" of muslims. North koreans kidnap or kill people because their "dignity" is insulted. Following that logic, aren't neo-nazis human? Don't they deserve "dignity"?
It isn't facebook that needs fixing. It is germany. What germans, chinese, saudis, russians, the extreme liberals and those who are anti-free speech don't understand that free speech is a necessary component of human dignity. You can't have human dignity without it. It is an essential characteristic of human dignity.
