likely to cause resentment or anger
invidious - unpleasant
If something, like an act, thought, or opinion is ‘invidious’, then it is likely to be unpleasant and cause offence to others. The word can also be used to express a comparison that is considered to be unfair or discriminatory. Not to be confused with the similarly spelt ‘insidious’, which means ‘gradually causing harm’.
