What blanket false statement? All I did was offer my opinion based on MY experience. I have worked with chondros since 1993 and began keeping them in 1994. I've had lots of chondros in that time. Many imports and many more CBB. My experience is what it is, not what has been published in this book or that. Most people that keep chondros, or have kept any number of locales would probably say the same thing.
And yes, geographic locality can affect the behavioral personality of an animal. Study the landscape of Biak and you'll understand why Biaks are a bit more aggressive than other locales. It has nothing to do with social culture but has everything to do with habitat and genetics.
As for stereotyping locales, if you know what you are looking at you can usually tell what region the animal comes from. Sure there are overlapping areas, but I can tell a sorong from a jaya from an aru. There is a reason we use the term locality "type".
If you ever get a chance, read Dr. David Wilson's study on chondros in the wild. You will find some surprising data in his research.
