Free speech isn't for everyone. That's fine, some people will prefer to bury their heads in the sand and never hear an opposing opinion in their life. That's okay, but we can't shut down the entire infrastructure of digital communication just because X group's feelings got hurt. They need to leave or accept the nature of digital communication for what it is.
Free speech is perfectly balanced and fair. First of all, ideas don't harm people, actions do. 1s and 0s on a dimly lit monitor have no impact on physical reality.
Second, ideas exist outside of communication. Just because someone doesn't articulate it, it doesn't mean that people won't think that way. Even if everyone doesn't think that way, it doesn't stop something from conceptualizing the idea or even the idea occurring by accident.
Third, if your tactful and clever, you can defuse any radical claim. Just because you don't have that tact or social finesse, doesn't mean you get to kill a platform for everyone else using it.
Finally, you can choose to be anonymous and utilize a disposable identity. If you really feel that an idea is harming you, press the power button and disassociate your online persona from yourself.
So annoying to see what is happening over in European countries over this crap. I would be less peeved if it was at least an intelligent power grab, but this is just blatant short-sighted, animalistic thinking that if you stop people from saying something the idea will just go away.
