I’m not trying to find someone to blame - I’ve already found them.

... Please consider being a serious person.

And it’s interesting that “people who actually want to affect change” wouldn’t want to try to tackle the actual problems.

Wagging your finger at individuals is never, ever going to solve the problem.

Identifying systemic changes, and advocating for them politically, will.

I guess it’s easier to point to single-target big bad entities rather than a more vague entity like…everyone.

Again. You are focusing on blame and pointing fingers. Nobody cares who you want to blame.

Also it is easier to pretend people don’t have agency, isn’t it?

Nowhere has I said that people don't have agency. I said that people's behaviour is shaped by the systems they live under, which is a trivially true observation.

So if we want to effect change on a scale large enough to actually make a difference, we will focus on systemic changes.
