In Australia we've just essentially criminalised climate protesting. Climate protestors now risk a huge fine and even jail time. A lot of people suspect it's because governments are preparing in advance for what might become a huge movement that they can't control. So they're trying to disincentivise people before shit hits the fan.
I don't get why people support AOC, as far as I can tell after she blatantly ignored New Yorkers who are fed up with the current migrant crisis. She's not open for debate, she's just pushing her own agenda.
