You're missing the point, the problem that is if you're trying to offer credible expert opinion on how to deal with a crisis, you undermine those opinions by introducing a highly charged political wedge issue that offers no solutions to the problem at hand.

Sure, you can argue that single-payer healthcare would have been good to solve this crisis and others would certainly argue that it would make things worse, but the debate is totally fruitless because implementing such a system will take years--well after coronavirus is either endemic or wiped out. Thus, even bringing it up makes me question whether you, as an expert, are capable of divorcing your personal bias from your scientific objectivity. I immediately think, "is this person speaking from their objective expertise, or do they look for the data that satisfies their political arguments, and ignoring the rest?"

Scientists should tell people the facts as objectively as possible because that is the purpose of the field and discipline. Leave activism to others, who will use the facts to come to whatever conclusions they can.
