The word "Haredi" is often used in the Jewish diaspora in place of the term "ultra-Orthodox", which many view as inaccurate or offensive, it being seen as a derogatory term suggesting extremism; English-language alternatives that have been proposed include "fervently Orthodox", "strictly Orthodox", or "traditional Orthodox". Others, however, dispute the characterization of the term as pejorative. Ari L. Goldman, a professor at Columbia University, notes that the term simply serves a practical purpose to distinguish a specific part of the Orthodox community, and is not meant as pejorative. Others, such as Samuel Heilman, criticized terms such as "ultra-Orthodox" and "traditional Orthodox", arguing that they misidentify Haredi Jews as more authentically Orthodox than others, as opposed to adopting customs and practises that reflect their desire to separate from the outside world.
