Well... individually there's probably things that make one an anti vaxxer or a climate change denier. Collectively though, it's collective suicide in the fact that both climate change denialism and anti vaxx affects people's lives. There is something suicidal in that fact and misery does love company. Collectively, it's a wish that we all die subconsciously out of being miserable. Those who cherish where they live, don't treat it like sh-t.
