I kind of disagree. These model, at least within the context of a public unvetted chat application should just refuse to engage. "I'm sorry I am not qualified to discuss on the merit of alternative medicine" is direct, fair and reduces the risk for the user on the other side. You never know the oucome of pushing back, and clearly outlining the limitation of the model seem the most appropriate action long term, even for the user own enlightment about the tech.
people just don't want to use a model that refuses to interact. it's that simple. in your exemple it's not hard for your model to behave like it disagrees but understands your perspective, like a normal friendly human would
