I think there is a similarity between both statements. The issue as I see it comes when people have strong opinions not based in commonly agreed upon facts.

So what we end up having is person A saying "we should get rid of ABC, it causes XYZ!", and person B says "ABC is amazing! Everyone should have ABC! The XYZ claim is overblown conspiracy", both opinions are very strong. But they don't agree on whether ABC causes XYZ. Before an intelligent conversation happens, the basis in fact has to be agreed upon.

This is basically impossible with non-falsifiable claims. But non-falsifiable claims generally means "there is no evidence for it". Because if a claim relies on evidence, then it is by default falsifiable. Show the evidence is wrong, and the claim disappears.

If there is no evidence... they didn't come to their beliefs through evidence. They came through some other means. Find out THOSE reasons, and you can have a fruitful discussion.

I've had plenty of fruitful discussions about politics just as I have about religion. The key in both cases is finding that reasoning. In both cases that reasoning is almost never the topic at hand. Don't start a political conversation with slavery. Start it with... idk... maybe what news outlets they pay attention to.
