I have to wonder if there is a change in the general level of emotional maturity in society or if things like the pseudo anonymity and immediacy of the virtual forum just make it much more apparent.
I am not sure - but I suspect that when there is more real-life interaction, people are exposed to a wider range of feedback and randomization that enhances learning. The internet allows for picking and choosing to create echo chambers that are further fed by algorithms.
Important point... it seems like that randomization is precisely what's missing from perspectives. People gravitate towards their echo chambers and then start operating under the false assumption that "most people think this way" because within their small slice that IS true, but it doesn't hold true on a broader scale.
And then there is the issue that even when they look a bit further, the algorithms are still feeding them more of the same.
True, if we’re not exposed to a range of opinions then whenever something triggers any cognitive dissonance We are probably more likely to have an emotional reaction
