I am very much pro free speech. In the sense of nothing should be disallowed. I think platforms should be built in a way that there really cannot arise an ultra-(right/left/X) bubble. Facebook should build mechanisms like they can be found here on HN. If I would write something really offensive I'd get downvoted and eventually my post would vanish. That feedback by the community is extremely important, because I get to learn what goes and what not. Just deleting unwanted opinions makes things worse. People build up aggression against "the system" and feel censored by the wrong mechanisms. If I, however, see that the majority dislikes my opinions I know where the problem is.
