Socialism.
Our Founders gave us a Constitutional Republic. This is meant to accomplish limited government overseen by people who are recognized as capable of making the most important decisions affecting our nation.
"Democracy" has been described as "two wolves and a sheep deciding what is for dinner". The evil that a majority will do to a minority has been recognized for many centuries. It is only judicial activism that has allowed many of the evils of democracy to infect our republic. The effects are so widespread and pervasive now, and the public educators so collectivist in mindset, that the distinction has almost disappeared.
How else can one explain the all-to-common acceptance of states deciding by majority vote whether the people shall be allowed to keep and bear arms?
