You still don't understand the word ' Farang ' and obviously you are not trying to understand it. It is exactly the same as when farangs call an Asian, Asian which I don't think it is racism. Similarly, when you talk about flowers you would call rose, daisy, sunflower, etc...so you know exactly what you are referring to. Which is the same when you talk about people; we just need to know their character you can't just say 'do not do what non-thais do' as it is to broad.
