Expert Long Rester
I would contend there are people I think need help with a topic who disagree with me (e.g. my children). I am assuming those folks need me. It's usually on me to know when its appropriate to insist on helping them and when it's better to step back, treat them as equals, or simply let them make mistakes.
Many adults, myself included, do not enjoy being treated like children, whom you used in your example.
If I ever feel like I should "insist on helping" what I should really do is ask whether or not they would like help. And that's true whether it's a D&D game, a car broken down on the side of the road, or a person at the gym.
I should never insist. I should ask. Because these adults are in fact not my children.
