We already live in a fascist world, and don’t need the aggravation of ‘eco-fascism’ as a divisive idea.
The everyday pressure on people to have kids, and a good job is incredible. From parents, to relatives all pushing the idea. To people feeling incredible insecure about not being able to describe themselves by their work title.
We live in fascist country dictated by nice aunts saying ‘so are you thinking of having a kid’, and ‘how is work going’? All while passing judgement.
Try for once to not conform; not have kids, not be a good bread-winner, and you will see the incredible psychological toll it takes.
This is the meaning of fascism. It is not militarism, or physically forcing a person to do something. It is a totalitarian system that devalues you, if you are not part of it. It is your aunt, neighbour, employer, all looking down on you if you do not conform.
We need people to stop having kids, we need people to stop and rethink the structure of their family. Who their friends are and why. How they evaluate themselves. Perhaps this is what you mean by social ecology.
You confuse the short physical pain of getting people to bicycle, with the deep physiological games of having people conform to a ‘normal life’. The first is simply policing, the other is a complex police state.
