Censoring divergent viewpoints is never an option in civilizations because it's uncivilized. It's juvenile, reptilian-brained, and sanctimonious. As adults, we should know and do better than cease communication via a phone hang-up, a social media block, a slammed door, or other such dismissive acts that let you know you are no longer worthy of being heard.
The information superhighway can lead you to a more evolved mind if you avoid lazy thinking, research your sources, and search out divergent opinions so you can fully understand the issue at hand. A closed mind is a dying mind and, in this day and age, there is no reason why we should not be getting bigger brains and traveling the super highway together on a tremendous road trip every single day.
