Yes, good to see a positive thread about the Thai people in general.
I have been living in various parts of Thailand for 22 years and my position on Thai people, without comparing with anywhere else, is just about 100% positive.
If I were to make an observation about the negative attitudes of many Farang, I would say that most complaints come from those who live in areas where there is a large population of resident foreigners and of course many tourists. This has the effect of local Thai people having their daily life culture compromised and more likely for conflict to occur and subsequent complaints arising.
Most of the reporting of these conflicts originate from Pattaya, Phuket, to a lesser extent around Chiang Mai, and parts of Bangkok.
For those of us who live in areas of Thailand where there are few tourists and foreign residents; we are more immersed in everyday Thai life so they and said foreign residents co-exist in an atmosphere of easier tolerance of our differences!
