Yeah you are right. But lots of my friends which are as old as I am (30 years), do speak chinese dialect. Most of them were not born in China. They use it with their parents to talk about something that they don't want 'ordinary' people to understand. But yes, MOST of Indonesian Chinese don't speak chinese.
And please don't use word 'Indon', we take that word as humiliation. I know you don't mean it. But please just use 'Indonesia'.
The original of this quote seems to have disappeared. From Coh Hiangswe's quote, it would appear that xng wrote it, but normally, these things don't disappear, or if they do, there will be a trace left of "edited x times". Perhaps it was said in another topic, but the content implies it's connected with this one. I'm stil puzzled by who actually said this originally.
