What do we mean by "doomer," here? Because the so-called optimists I meet are the ones who actually act like "better things aren't possible." The people I know who claim to be happy may as well be saying "Fuck you, I got mine," since they seem to be the least likely to give a shit about the world's problems. Whereas absolute pessimism and relentless negativity are perfectly sober ways of looking at the world, as long as they don't lead to resignation and inactivity.
