It’s not just anger. The majority of voters take actual delight in harming others, even when the cost of doing so is harming themselves too.
Collectively, humans are evil to the core. That’s the problem that Trump is a symptom of - even if he chokes to death on Putin’s dick right now the problem isn’t going to go away. Some other Nazi will fill in and the 73 million traitors that voted for Trump will just redirect their support to the next guy.
I’ve been wondering that myself.
