I'm Peterson from Chicago. I'm native speaker and have been working in China for a couple of years too.

You sure you are a native speaker

I think everyone should be given the chance to teach or work, provided he or she is competent. We all studied and were all trained to be teachers. I believe we've got some schools in china who even desire non-natives to teach their students.
China is capitalized

Some schools say they need blacks because they are hard working. A good number of native speakers come to China simply because they had nothing to do back home. When they get to China, they become as proud as peacocks.

I wanna be more specific. Felix, doesn't want non-natives to teach english in China.
There should be no comma here. And English is capitalized

You are a native speaker but why not go back home?
Everyone has their own reasons for being here. Why don't YOU go back home if it comes to that?

You've been here for 5 years. Are you afraid to pay taxes and other bills? We are all whites and need not be so racist.

It is the LAW that Foreign teachers be native speakers...nothing to do with being racist

We are all foreigners in an unknown land. Do you think we are the best teachers? Some native speakers can't even spell words correctly and rely on their colleagues who are non-natives. A Canadian writes for machine, an Australian writes for chair.

What are you trying to say in the last sentence? It makes no sense at all.[/i[

They're all teachers in China and wrote the dogshit on the blackboard for students to copy. Some natives love china because they've got no jobs back home, afraid to pay bills and do not even have homes.
China is capitalized

They're happy in China because everything is free.

Guys, we're all native speakers but that shouldn't make us proud. Man has equal rights. Non-natives even taught some of us before we came to China

I could go on pointing out mistakes but I think I have made my point. You are NOT a native speaker. You make mistakes that no native speaker would ever make. Once more...it is the LAW in China that you be a native speaker. Got it? Now back home you go. Thank you.
