I was thinking about the meaning of "acceptance" recently. It means you feel some injustice or frustration about something. Morally, you think the problem should be fixed, but strategically you think you shouldn't try.
Everything we do has limits and obstacles. If you don't feel frustrated, then that's a completely ordinary situation and there's no point in highlighting your "acceptance", is there?
I suppose in tech terms it could be equivalent to "won't fix", but such matters should be swiftly forgotten. If you're experiencing ongoing acceptance, consciously, that's suboptimal and implies you'd still be right to complain.
Thus recommending acceptance to somebody is recommending defeat. The term acceptance entails bottled-up frustration or injustice. It may still be strategically right, but it's a twisted, contingent choice.
No moral or injustice component needed.
I have genetic chronic fatigue and I’m limited in what I can do about it, there is a component of making peace with loss, a radical acceptance of one’s own situation. And there is a component of extreme experimentation, I have done just about all that can be done about it. I have to give up on my dreams of athleticism. Life isn’t fair, it’s life, but I wouldn’t call it an injustice. I think the modern conflation is part of making the personal political.
I put "frustration" in there for a reason. There are situations that are nobody's fault, which we shrug about. Then there are other situations that are nobody's fault, about which we think "something should be done", even though it's nobody's particular duty to fix the problem. That lingering frustration is a moral opinion. It's informed by expectations and realism, which it is often beyond our grasp to even determine accurately.
