It’s not different for the Internet. We’ve always had people that have been opposed to ideologies separate from their own. Book bans aren’t anything new and neither are restrictions to free speech. Nazi book burnings and the US Red Scare are extreme examples of this. It’s all a symptom of nationalism and ethnocentrism, just a different place/time/media. What really sucks is that the nationalists have a lot of power now all over the world, and we’re slowly seeing the results of that.
