You resist the urge to "rage" by having empathy. In my experience, we in medicine are often out of touch with how much more we understand about medicine/science than the majority of the population. Instead of getting angry at these people for posting things like that, we should use it as an opportunity to educate. Even though it is so simple to us in the science world that the picture is completely inaccurate, it is not obvious to people outside of our bubble.
And I don't mean this in a condescending way nor am I trying to suggest that we are superior to the rest of the public. I guarantee there are concepts that are simple for hairdressers/business people/lawyers/meteorologists/etc to understand that many of us in medicine don't understand. Encouraging others (and ourselves) to be resourceful and fact-check things like this or like vaccinations is more productive than "raging". We all bring something unique to the table.
Also, while this post may seem unnecessarily serious, this topic is salient to me as I've recently seen many peers look down on people outside of medicine. We are not holier than thou and need to remember that everyone contributes something.
