A hate group is an organized group or movement that advocates and practices hatred, hostility, or violence towards members of a race, ethnicity, nation, religion, gender, gender identity, sexual orientation or any other designated sector of society. According to the United States Federal Bureau of Investigation (FBI), a hate group's "primary purpose is to promote animosity, hostility, and malice against persons belonging to a race, religion, disability, sexual orientation, or ethnicity/national origin which differs from that of the members of the organization." Scholars find it difficult to define the term hate group and "whether a particular group is to be classified as a hate group is sometimes in the eye of the beholder."
