The Greens are an ideological fear movement, they use fear as an argument because they have no arguments. As they do with a nuclear catastrophe and climate change, they are primarily stoking and abusing the fears of our weakest, the children, to push their agenda.
For Greens to succeed, people must fear. The Greens are the party that persuades children that there is a monster lurking in the closet to make parents toe the line.
This is the kind of fear propaganda with which the Greens try to scare their children.
