Right-wing populism by those who support ethnocentrism ( usually white nationalism ) and oppose immigration creates a climate of " us versus them " leading to radicalization . The growth of white nationalism in a political climate of polarization has provided an opportunity for both on - and offline radicalization and recruitment as an alternative to increasingly distrusted traditional mainstream choices . In 2009 , the United States Department of Homeland Security identified economic and political conditions as leading to a rise in right-wing radicalization and recruitment . The Anti-Defamation League reports that white supremacist propaganda and recruitment efforts on and around college campuses have been increasing sharply , with 1,187 incidents in 2018 compared to 421 in 2017 , far exceeding any previous year . Far-right terrorists rely on a variety of strategies such as leafleting , violent rituals , and house parties to recruit , targeting angry and marginalized youth looking for solutions to their problems . But their most effective recruitment tool is extremist music , which avoids monitoring by moderating parties such as parents and school authorities . Risk factors for recruitment include exposure to racism during childhood , dysfunctional families such as divorced parents , physical , emotional , and sexual abuse , neglect , and disillusionment . In 2018 , researchers from the Data & Society think tank identified the YouTube recommendation system as promoting a range of political positions from mainstream libertarianism and conservatism to overt white nationalism . Many other online discussion groups and forums are used for online right-wing radicalization . Facebook was found to be offering advertisements targeted to 168,000 users in a white genocide conspiracy theory category , which they removed shortly after being contacted by journalists in the wake of the 2018 Pittsburgh synagogue shooting . After the March 15 2019 Christchurch mosque shootings , Facebook announced that they have banned white nationalist and white separatist content along with white supremacy
