Scholars have defined Fascism as: "A mass movement, that combines different classes but is prevalently of the middle classes, which sees itself as having a mission of national regeneration, is in a state of war with its adversaries and seeks a monopoly of power by using terror, parliamentary tactics and compromise to create a new regime, destroying democracy."
"“Other characteristics on most scholars' checklists: the rejection of both liberalism and socialism; the primacy of the nation over the rights of the individual; the demonization of the nation's enemies; the elimination of dissent and the creation of a single-party state; the dominant role of a charismatic leader; the appeal to emotion and myth rather than reason; the glorification of violence on behalf of a national cause; the mobilization and militarization of civil society; an expansionist foreign policy intended to promote national greatness.”" 
Many of these characteristics are (at least arguably, and in accordance with the thesis of those who use the term Islamofascism) attributable to certain self-described-as-Islamic regimes and miltant organizations.--FRS 20:48, 17 January 2006 (UTC)
Some political scientists have defined Islamofascism as totalitarian rule where members of a nation (a nation actually is a group of people having a common identity and both Jews and Muslims constitute a borderless and stateless nation) are forbidden from renouncing citizenship in the nation. Doing so is treason (aka murtad or apostacy) that is punishable by death.
Both Fascism and Islamism are against the liberty principle as we know it, and that it's up to the Government to directly decide what's right and what's wrong. The main difference between them is that Fascism uses political and economical excuses to justify its existance, and Islamism uses religious excuses. --IAmNav 21:42, 14 April 2009 (UTC)
