You should exercise nore temperance. It is futile to hate things you can't control.
There is are discontinuous, spectrum of limits to locus-of-control. It's important not to fall into either trap of absolutist internal or external LoC. I think there are generally too many people in wider humanity who adopt defeatist, learned helplessness, external local-of-control attitudes through sayings like "it's God's will" or "you can't fight city hall".
Doing what you can control and focusing on that, doesn't mean that you also don't speak up for change, because that is entirely something you can still control. In fact it's encouraged, because of stoic 'virtue', "That which you do the right thing, that is all that matters"
If others are using it to shut up up, that is what is outside of your control, you ignore it and do the right thing anyway.
Under stoicism, you would still push and advocate for change as an individual, but you would understand that if the world doesn't change or doesn't respond, that is out of your control, but you can and should still excuse your right to do that, because that is within your control.
The entire argument here seems to be missing the point.
