Not under these circumstances, no. Part of understanding that the world is not sane, is understanding that some people in any given reference class will refuse to be persuaded by any given bit of sanity. It might be worrying if the object-level case against single-world QM were not absolutely clear-cut.

It may be worth also observing that at least two of those users have disagreements with you about epistemology and reductionism far more fundamental than QM interpretations. When someone's epistemic philosophy leads them to disagree about existence implications of general relativity then their epistemic disagreement about the implications of QM provides very little additional information.

When you bite the bullet and accept someone else's beliefs based on their authority then consistency suggests you do it at the core point of disagreement, not merely one of the implications thereof. In this case that would require rather sweeping changes.
