Fascist and similar ideological movements have achieved and continue to achieve worldwide success by threatening the fundamental values that are most important to communities and nations. The most likely to provoke a visceral reaction are allegations that threaten the identity of the targeted group. The majority of people react instinctively to verbal attacks on national, gender, racial, religious, family, generational, ideological, existential, political, and thus fundamental identities. As Federico Finchelstein states in his book Fascist Lies, "One of the most important lessons of the history of fascism is that racist lies lead to extreme, politically motivated violence."
