I didn't try to force him to try to change who he was, I just disagreed with his statements. I also explained why I disagreed with them. I didn't call him names or make disparaging comments of any kind about his nationality!
I think that I debated the issues politely.
How am I "ethnocentric"? I'm not judging his nationality, just defending my own!
Ethnocentrism is judging another culture solely by the values and standards of one's own culture.

Show me a post of mine anywhere on this forum that judges or disparages any nationality or ethnicity.
