>I wonder why facebook usage isn't "sowing discord"

Because it's not Facebook.

Notice that in US, one side (Democrats, media conglomerates and their 'journalist' employees) are pushing for Facebook to censor, de-platform, or 'rank down' independent, conservative and progressive outlets. It is this group, author of the post included, that keeps calling Facebook, YouTube, Twitter (and even first amendment) divisive or undemocratic as a cynical, self-serving strategy to move the needle in their direction (for Democrats, it means more political power, for media conglomerates, it means less competition for eyeballs, and more revenue).

Meanwhile conservative and progressive outlets are calling for less Facebook censorship because they see themselves under constant attack, even when they report factually correct news.
