Is there is a word that describes vehement disdain for people who are perceived to have a lower social status than one's self? I'm looking for a word that is to class-ism as bigotry is to racism.
Haughtiness might work.
Haughty (the adjective form) means "having or showing arrogant superiority to and disdain of those one views as unworthy."
Bigotry is to classism as bigotry is to racism.
Bigotry now refers to “the practice of having very strong and unreasonable opinions, especially about politics, race, or religion, and refusing to consider other people's opinions”.²
