A sector of Germany's population is extremely racist, while other Germans have organized to defend migrant and refugee rights, among others. However, over half a century after Adolf Hitler's effort to eliminate all “impure races” from the country, ordering the genocide of millions of Jewish people, many Germans still believe in white supremacy. The Neo-Nazis still exist today and openly talk about anti-Semitic ideas. In 2011, a study by the Institute for Interdisciplinary Research found 47.1 percent of Germans believe there are too many foreigners in the country. Nearly 30 percent agreed foreigners should be removed from Germany if jobs became scarce.
