Would you like to educate someone? If not..check this out anyway...?

This is not meant to be taken as a person being racist. But to those with this problem doesn't it get annoying to have to say: I'm dominican not puerto rican? Or I'm vietnamese not chinese? Well, to some people I have known, it did. And they voiced it when it did. So instead of letting ignorance continue...why not educate a sista? To the hispanic people and the asian people, and anyone who knows... Could you please explain to me/show me, how to distinguish the differences and characteristics of the many different races? Seriousness here people. If you are going to be rude, and or racially insensitive do not comment at all, you will be reported. Oh and Yes there is always the option of asking a person what ethnicity they are, but sometimes that is a bad idea. Sometimes people can get a bit offended when you do that. I wouldn't want some person coming up to me saying what tribe am I from >> ... lol So please don't leave an answer like "just ask them"...
