I don't call you fascist because I have a difference of opinion, fascist is:

Here's the wikipedia definition of it:

Fascism, pronounced /ˈfæʃɪzəm/, comprises a radical and authoritarian nationalist political ideology^[1][2][3][4] and a corporatist economic ideology.^[5] (Corporation: the authoritarian government)

Fascists advocate the creation of a single-party state.^[6] (Party of God!)

Fascists believe that nations and/or races are in perpetual conflict whereby only the strong can survive by being healthy, vital, and by asserting themselves in conflict against the weak.^[7] 

Fascist governments forbid and suppress criticism and opposition to the government and the fascist movement.^[8] 

Fascism opposes class conflict, blames capitalist liberal democracies for its creation and communists for exploiting the concept.^[9] 

Fascism is much defined by what it opposes, what scholars call the fascist negations - its opposition to individualism^[10], rationalism, liberalism, conservatism, capitalism, and communism. ^[11][12] 

In the economic sphere, many fascist leaders have claimed to support a "Third Way" in economic policy, which they believed superior to both the rampant individualism of unrestrained capitalism and the severe control ofstate communism.^[13][14] 

This was to be achieved by a form of government control over business and labour (called "the corporate state" by Mussolini).^[15][16] 

No common and concise definition exists for fascism and historians and political scientists disagree on what should be in any concise definition.^[17] (However, Mr Ahmadinejad, and his mouthpiece here, Pen Name, vey well fit the stereotypical definistions above!)
