Guns

Gun Rights Side

 * Republican state legislator Mike Leara introduced legislation in Missouri to make it a felony, punishable by imprisonment, for any lawmaker to propose any gun control legislation.
 * The president of the Gun Owners of America believes Obama plans to take peoples' guns as part of a plot to build a black army to kill white people.
 * The Tea Party and far-right "news" source Drudge Report call for an armed uprising against President Obama, comparing gun control efforts to Adolf Hitler and Joseph Stalin.
 * The National Rifle Association (NRA) has become increasingly extreme in its views, moving from focusing on hunting to calling all forms of gun control tyranny.

Terrorism

 * Terrorist group Al Qaeda has praised America for its lack of gun control, calling it "awash with easily obtainable firearms."

Research

 * Until 2013, there was a federal ban on government funding for research that could advocate for gun control.  One of the first major studies on the subject used mathematical models showing that a complete gun ban would save lives.  The same study showed that arming everyone would only save lives if everyone with a gun were properly trained so they wouldn't shoot innocents during mass shootings - but even now, current owners are not properly trained.

Major Incidents
A list of mass shootings since Columbine is here available here.

Sandy Hook

 * Right-wing extremists have been harassing a man who helped students through the Sandy Hook incident with e-mails, phone calls, and physical mail accusing him of being a liar and paid actor, with many posting his personal information online to encourage others to harass him as well.
 * Gun advocates planned a gun appreciation event at a Newtown Starbucks, the same city that Sandy Hook occurred in.

The Second Amendment

 * The Second Amendment was Ratified to Preserve Slavery
 * NRA’s constitutional fraud: The truth behind the “right to bear arms”
 * The Second Amendment of the United States Constitution protects the right of gun owners to bear arms, but it also provides for government regulation of that right.
 * The First Amendment guarantees free speech, but people do not have a Constitutional right to yell "fire" in a crowded theater or to make specific threats of violence.  Likewise, the guarantee of gun rights does not grant a Constitutional right to any gun at all in every situation.
