People don’t speak “Mexican”, they speak “Spanish”.
If someone is Chinese, Japanese, Korean, etc., and you don’t know where they are from, don’t just call them “Chinese”, it’s “Asian”.
The following terms are not ok to use under any circumstances…”Colored”, “Negro” and the N word.
The term “Jew ’em down” is offensive. Try “negotiate” or even “haggle ” or “dicker”.
Don’t visit Mexico and call the U.S. “America”, Mexico is in America too, and so is all of South AMERICA.
Don’t call people or things “gay” or “retarded” as a joke. It’s not funny.
An “Indian” is someone from India, not someone of Native American decent.
And to all you white Americans of European decent whose family has been here for a few measly generations and think you are the “real” Americans, the only “real” Americans are the original Americans, Native Americans.
These are just off the top of my head. That’s all I have to say at the moment. However, please feel free to add to this list.
