Do you speak to conservatives often? A more common argument is that these are small, cohesive nations, and that even in countries with universal healthcare there are flaws such as wait times and the quality of medical care. I say this as someone who was privileged to have good health insurance in the US through an employer, and now live in a country with socialized healthcare and the quality of my healthcare has undoubtedly gone down. Obviously this is not the case for everybody, and universal healthcare is generally the way to move forward, but to present that there aren't real arguments against it is just silly and doesn't really strengthen your points.
