I’d argue that hating concepts can lead to productive societal growth, and could even lead to personal growth depending on what is hated and for what reason.
For example, I hate capitalism, corruption, greed etc., which led me to learn more about alternatives that I would have not learned about otherwise. This could also go both ways, though, since hate for the exact same things have also led people down a fascist road, as human nature makes it so that we always want an enemy to blame. Whether that enemy is the ultra-wealthy or whether it’s the common man (ex: trans people, women, immigrants, etc.) is largely dictated by the media they consume and the people they surround themselves with.
Mob mentality is alive and well, and it’s up to all of us (as non-billionaires) to focus that energy in the correct places. Billionaires are the ones who started the culture war and keep feeding it, since that distracts normal people away from themselves, since they know that if they didn’t give the masses a group to hate (the common man), that they would find their own group to hate (billiomaires).
There’s a reason Luigi has so much support even though he allegedly murdered someone.
Economic instability will always lead to resentment over something and/or someone/group.
