They get what they vote. I met my oldest Aussie friends more than 20 years ago, in college, and they were already outlandishly leftist, in the bad, current sense of the word.
Ecogreenfemo-fascists in the making, just that even they seemed to think that it was just a youth phase and that the crazies would never really take over. Mostly a typical case of very affluent white Anglo kids posturing.
Boy were we all fucking wrong about it.
