*"Chemtrails"—this appears to be one of the "New World Order" conspiracy theories. It says that some entity (the U.S. government? the New World Order?) is seeding the atmosphere with chemicals for weather manipulation, mind control, or some other purpose. Evidence of this can be seen in what normal people would consider to be the condensation trails (contrails) of high-flying aircraft.<ref>http://weatherwars.info/</ref> Some variants of this have suggested that what normal people call cell phone towers are in fact put in place for some other sinister purpose.
*Highway signs—another one of the "New World Order" conspiracy theories. It says that the tiny numbers in the lower corners of direction signs on interstate highways are actually put in place to guide the military vehicles that will be used in some kind of invasion of the United States. The invasion is expected to come from the United Nations, some foreign government, or some other internationalist entity.
*The [[Newtown|Sandy Hook massacre conspiracy theory]], which claims that the massacre did not occur, and was a "false flag" operation by the federal government. This theory is quite difficult to accept, since it requires believing that the 26 victims never existed, a notion that their families do not appreciate. This, in turn, has led to some lawsuits and criminal actions. [[Alex Jones]] is perhaps this theory's main proponent. There are similar conspiracy theories about the shooting at Marjory Stoneman Douglas High School.
*That [[Queen Elizabeth II]] is/was running a drug cartel in England. This one dates back to the 1980's, and appears to have originated with [[Lyndon Larouche]]. It is currently embraced by Jacques Cheminade, a Larouche follower and current candidate for the presidency of France.
*If a president of his quality and insight has failed, it must be because his opponents are uniquely evil, coordinated and effective. The problem is not [[Bill Clinton]] or [[Barack Hussein Obama]] but an imaginary "[[conservative]] conspiracy" against them.<ref>[http://www.washingtonpost.com/wp-dyn/content/article/2010/11/25/AR2010112502553.html?wpisrc=nl_opinions Washington Post; Liberals resort to conspiracy theories to explain Obama's problems]</ref>
