You are not wrong. The widespread misinforming of people re: gun facts is widely known by the media themselves. (Slate even admitted this in an article sev. years ago “If the media wants a healthy conversation about firearm laws, it needs to stop getting basic gun facts wrong”. (The Media Keeps Misfiring When It Writes About Guns
What is interesting is that Slate here is admitting it is not only true, but known to be true, widely known, virtually taken for granted among the media themselves. This begs the question: If getting their facts wrong is a known problem why not correct it? The answer is obvious and suggests these inaccuracies are not errors but deliberate, and on purpose.
If you know there is a widespread problem of false information, ignorance, and bias among your own industry, and do not correct it, when the tools to do so including research staff are at your fingertips, it is deliberate.
