[picks up history textbook]
[reading] Oh no.
[flips a few pages ahead] Oh no. Oh dear.

perhaps it's some confirmation bias -- it being easier to write, both contemporarily and in hindsight, about the year a war kicked off than the years of fuckall happening before it -- but no I'm fairly confident at least half of all of us are proper assholes, possibly more than half, and always have been; personal learned experience has further reinforced this. Misanthropy is only really unhealthy for oneself when you don't know who you should be directing that anger at.
