The 68’s movement, MLK, German unification come to mind. What they, however, had in common was that violence was on the table or at least a plausible development. Those in power just figured that gunning down citizens wouldn’t be in their best long term interest.

It is not my company.

Counterexample: Rome, most European countries in fact, plenty of Asian countries which started in fertile lands etc

You seem to be borderline panicking. Take a few deep breaths, and then remember the following:

1. The past is gone, the future is uncertain.
2. Never let perfect get in the way of good.
3. Pick your battles.

Now, with that out of the way: you cannot undo the past. Don’t try to.

So, the question is, what do you do? I am not bothering with tech answers, there are plenty of guides online.

Therefore: Go and see if there are knowledgeable people around you who have no reason to harm you. Go to your local hackerspace, repair cafe, civil rights group, whatever you may have close and looks acceptable. Listen to advice, and if necessary quietly discard the bits you think are stupid.

Yes, even if they are all weird neckbeards or furry trans wannabe catgirls or tree-hugging hippies. Nod and smile and just talk “shop”, if you have to. And there is no shame in accepting that you disagree too much with a group and won’t come back.

We are not supposed to face things alone. Sitting alone and panicking is a way that leads to tinfoil hats and lizard people. And everyone fighting on their own, divide and conquer, that is how movements fail.
