When Korean heard chino or similar word,we think you are racist or didn't study about it.
There is something between Arg and Mexico I have picked that up over the years. Just tell the Asians to reply with Mexicito when they are called Chinitos. I would love to be a fly when watching such and interaction.No doubt all the so proud to be EUROPEAN Argentinians won't mind if I start calling them all little Mexicans. Hey it's all all meant to be endearing, Argentinians are above PC, and at least Mexicans and Argentinians speak the same language!
Chinito needs something more than if you insult like “de mierda”, etc, because it is not pejorative by itself as I already explains.I find interesting that after several days no one was able to give a detailed answer about how to identify bad speak so we can all stop doing it.
I guess it just shows how complex of a problem it is. At the root trying to define bad speak is so subjective and filled with so many cultural and interpersonal nuances that it cannot realistically be done.
