today I met someone who is girl and from Japan.
she talk to me

first.
she said, "korean men are dumb."
and I said, "aren't we?"
she said again, "korean men doesn't learning anything. everybody know about."

Yeah, that is totally words base on the nationality and race and sex.
and I said to her, "i think your opinion is hasty generalization."
suddenly, she upset to me. "I'm not a Japanese, you think I hate koreans because I'm Japanese,
you are child, you don't have a open and smart mind... blah blah blah..."

first, I don't said to her like "maybe you are from Japan, and then you hate korea."
doesn't matter about she is nationality and race and sex to me..
why??
no one cannot judge the people by nationality and race and sex with prove of methodology of science.

second
No, I'm not a child.
