The internet and social media has made it much easier for everyone to wall themselves off into groups containing people with only their viewpoint.

It’s not people who share your viewpoints, unless you buy into the artificial left/right dichotomy and are willing to simply accept whatever popular talking points permeate your silo. Conversely, if you actually wanted to share a space online with only people who are actually from your own country, or even just western society broadly, such a thing doesn’t exist at all. While the issues of political division within America are significant, what flies completely under the radar is how trivial it is for bad actors from places like Russia and China to participate freely in political debates, often without anyone actually being aware of it.
