This is the right takeaway. Before the internet went mainstream, these ultra loud and obnoxious minorities were restricted to being obnoxious within their local communities, and their speech was restricted to what they were willing to say to others face-to-face.

Now, both of those restrictions have been lifted: they can now act obnoxious in front of a global audience that will be forced to listen to them, and they no longer have to worry about the potential consequences of being obnoxious in person.
