I would disagree about proverbial masks. Majority of people in the world including US are simply too preoccupied with their everyday routine, problems and work to end up with extreme political views.
What Internet does have is ease of changing masks and joining diverse groups. Trying something unusual without reprecussions appeal to a lot of people who usually simply dont have time to join such groups offline.
The real problem is that unfortunately propoganda has evolved too with all new research about human phychology, behaviors and fallacies. Abusing weaknesses of monkey brain on scale is relatively easy and profitable.
