Your main tool for shutting down opinions you disagree with is to say that you taught science. We've all seen it many times.

Hard science is over the heads of most readers and they're never going to approach it. Popular science journals offer the basics and more information and detail can be had by those who wish to find it. No cheap shot, just a frank appraisal of how you approach anything to do with science. From the Scientific American article:

Almost exactly four years earlier he and the CDC had sent an urgent bulletin to hospitals, telling them to be on the lookout. The fungus had not yet appeared in the U.S., but Chiller had been chatting with peers in other countries and had heard what happened when the microbe invaded their health-care systems. It resisted treatment by most of the few drugs that could be used against it. It thrived on cold hard surfaces and laughed at cleaning chemicals; some hospitals where it landed had to rip out equipment and walls to defeat it. It caused fast-spreading outbreaks and killed up to two thirds of the people who contracted it.

This writerly-style to general science writing gives a basic understanding of the problem. These are review articles that contain generalizations but also discuss specific studies. You the reader don't want to get this disease or condition, you want to know if it's out there, and you want to know more about how to prevent it. You're engaged.
