Rather, while bringing people together in virtual spaces does probably help different peoples see each other with empathy, and diminish tribalistic attitudes... The wrong people are in the chat. Every nation that goes to war is itself fractured into classes. The people who send a nation to war are different from those on the battlefield. Empathy for the enemy on the part of soldiers doesn't prevent them being compelled to violence.
Imagine a video of Yemeni people starving to death on the news, but they sound just like you and your loved ones. It feels like that would turn the empathy WAY up.
But maybe I'm tripping into the same optimistic pitfall.
Forums and chat rooms were nice because the communities were small and directed. People were jerks for sure but they weren’t getting points. Even among the jerks the communities were localized enough that the jerks that cared enough to stick around weren’t mere trolls.
