about Obama being "slave masters, kidnapped, raped, cheated, sell salves to white and made a good profit". It's also amazed me that a Chinese person can think like that (may be not, we had culture revolution anyway).

Do you remember some American said "all Chinese are spy!" during "Li Wen He" case? Do you think you can get away from discrimination if the world full of people like you? The way you saying about others in such a race way might come back to you someday.
