I would describe fundamentalism as, first of all, a movement led almost invariably by authoritarian males who consider themselves to be superior to others and who have an overwhelming commitment to subjugate women and to dominate their fellow believers.
Second, fundamentalists draw clear distinctions between themselves, the true believers, and others. They are convinced that they are right and that anyone who contradicts them is inferior and beyond the purview of God's full blessing.
Third, fundamentalists are militant in fighting against any challenge to their beliefs, are often angry and sometimes resort to verbal or even physical abuse against those who oppose the implementation of their agenda. Finally, they tend to make their self-definition narrow, to isolate themselves, to demagogue social and emotional issues and to view change, cooperation, negotiation or other efforts to resolve differences as signs of weakness."
