Extreme conservative is a term typically used to describe individuals who hold very right-wing views on social, economic, and political issues. However, there are several synonyms that convey different shades of meaning. A far-right ideologue is a person who holds extreme views but is dogmatic in their approach and may be unwilling to compromise. A fanatical conservative is someone who is zealous and passionate in their beliefs, often to the point of irrationality. A reactionary conservative is someone who seeks to undo progressive changes and return to traditional values. Finally, a radical conservative is someone who advocates for fundamental changes in the societal order and may be willing to use extreme methods to achieve their goals.
