I disagree.

People have a need to be heard and understood. That’s half of what we are doing here posting.

Many (“not disabled”) people don’t fit in with their local peer group / society. The internet gave them a way to connect with other like-minded individuals.

Do I need to give examples? Let’s say: struggling with a rare disease.

But on the other end you have genocide triggered by Facebook. You can't speak if you're dead.

Perhaps some of that violence would have happened anyway. I don't know how it all nets out.
