Rudeness

Yes

impoliteness, rudeness

Rudeness is simply rudeness. Rudeness does not favor a certain sex, race, color, age or ethnic background over another. If there is a discriminatory act, or a discriminatory comment involved along with rudeness, then the guilty party has committed two social offenses, not just the one.

That being said... rudeness and ignorance sadly become intertwined on a regular basis. Ignorance of cultural and regional customs can be construed by others as 'rudeness' and also as 'discrimination'.

It is possible there was genuine ignorance involved in the actions or comments seen as discrimination. Was it actually discrimination? Or was it simply rudeness? I can't answer the question fully not knowing the circumstances that lead to this question being posted.
