Shunned as soon as people from Asia

learned I am an Asian-American that don't speak their language.  These people from Asia are Asian language interpreters, mainly Korean and Vietnamese.   I kept it vague at this new volunteer place at the beginning; and when asked what race I am, I asked why do they want to know, and that I don't care about race, color, gender, or religion they are.  They were friendly toward me then.  Now they learned I am Chinese, they either ignored or shunned me.  Geez, how rude.
