Let me reframe my previous comment:

If you don’t want to network in person locally, you will need to find a forum whose sole purpose is activism and direct action.

It will not be brought to you, and you will not be recruited. You have to actively go seek it out.

The forum you’re on now is called “technology”. Similar ones, like “news” or literally any other topic that doesn’t solely focus on mobilizing activists will not get you what you’re asking for here.
