I'm an Ethiopian student at a university in the US. I have been living in this country for many years and I love it. However, I've noticed a certain trend in people's general reaction concerning my place of origin. I speak English with no accent. When people first meet me, they assume that I'm an American. As such they behave normal until I tell them that I am a citizen of Ethiopia. At this point pretty much all of them immediately seem to develop a sort of superiority complex and start treating me as if I were an inferior being. They seem to respect me less and tease me every way they can. My opinions (even professional ones) are rejected as unacceptable.
Frustrated with this extreme prejudice, I lied to some of these people and told them that I actually am an American and not an Ethiopian. I noticed immediately that their attitudes towards me changed and started treating me as an equal. Encouraged by the result of this little social experiment, I've shied away from telling my place of origin to people to avoid mistreatment. However, I feel guilty doing it. Was I discriminated against because of my place of origin? Any words of wisdom for me, dearest Alice?
