This question already has an answer here:
I'm looking for a word or phrase to describe someone who thinks that their perspective is the only one, or is the universal fixed norm against which all other perspectives are judged. They think that if they have never personally experienced something, it thereby doesn't exist.
An example is an older heterosexual white man who thinks that oppression hasn't existed in 100 years.
I'm looking for a better descriptor than "ignorant" or "narrow-minded." Thank you.
