The primary reason that "islamofascist" drives me nuts is that the relationship between religion and the State is totally different. In Fascism, the Church serves the State, as an agent of State power, and is subservient to the needs of the State. I don't think that's what Osama Bin Laden wants. In fact, it just about 180 degrees from it.
ODL and his ilk are theocrats, and by definition therefore are totalitarians. At least, I'm not aware of any free theocracies. But Fascists, they clearly are not. Fascism's ideology had some clearly-defined themes, here are the ones that leap to mind right now:
1. The inate superiority of "the nation" or "the people." This was more racial in Nazi ideology, where for Mussolini and Franco, I think it was more nationalistic. Might be wrong on that one, though.
2. The strong (see #1) not only deserve to rule over the weak, it is their duty to do so. The weaker should support and serve their superior masters.
3. While Fascism was not primarily an economic ideology, it had some economic ideas. Work is the duty of the citizen to the State. (like communism) The work of some is more valuable to the nation than that of others, and the citizens should be ranked accordingly. (not like communism) The economic power of business should be allied with the power of the State, and should be directed towards the glory and expansion of the Nation. If you get rich in the process, that's OK, as long as you do not betray the goals of the State for money, or use your wealth to challenge the State's power.
4. The natural goal and duty of the People and the Nation is to expand, pushing aside the weaker nations and taking their resources and lands. War, and specifically imperial war, is essential to Fascist ideology. In fact, Fascist social organization was all geared to the creation of a war machine, and the soldiers to make it go. Some inspiration was clearly taken from the Spartans, here.
5. Religion is seen as a means of social control. As long as the Church remains subservient to the State, and does not create a rival power base, it's tolerated, even encouraged. The three countries that had Fascist governments all had authoritarian religious traditions. Spain and Italy are heavily Roman Catholic, as was southern Germany. Northern Germany was Protestant, but the churches there had a long tradition of serving the will of the princes and kings.
Yes, "fascist" has come to mean "authoritarian", but it's a squares-and-rectangles kind of thing. All Fascists are authoritarians. Not all authoritarians are Fascists. I'm not trying to be pedantic, either. Fascism is a specific ideology, and one that will reappear. Since I consider it to be one of the most deadly ideologies ever dreamt up by the mind of man, I think it's important to know what it is, and what it is not. The last time it reared it's ugly head, it cost over 100 million people their lives. The way to not have to pay that butcher's bill again is to be able to recognize it when it comes, and kill it then.
I hope I didn't come across like I was trying to slap anyone down. I wasn't.
), have evolution taught in schools, have the ten commandments in the Court House, leave the cross in San Diego up. I want to profile Muslims, wipe my butt on the flag, put a crucifix in pee and let Mel Gibson rant. Im a big enough boy to take care of myself and I know who my enemies are.
