Does anybody know of any scientific, or for that matter historical theories that are taboo? I mean as in you aren't allowed to talk about them or they're considered too outlandish to even consider. That sort of thing.
There's a saying which goes : To learn who rules over you, simply find out who you are not allowed to criticize. With that in mind, would you say it's ever justified to set limits on speech when it comes to talking about scientific ideas, or for that matter historical events?
