There are people/trolls on social media (and I believe that includes this forum) from this country or another whose goal is to create problems and make the Right look like lunatics. They spread all kinds of kooky fake news, lies, and conspiracy theories. Be very skeptical! We are better than that. Don't believe everything just because you want to believe it cause it confirms your bias. Don't be lazy and do your own research. Sandy Hook was no hoax and anyone believing that is a real moron or a troll.
