Are you fluent in Thai?
Can you read it?
Why not?
Is it because you have low IQ?
Do you speak with Thai people in Thai?
Why not?
Why do you expect them to speak in English?
There's more than a hint of racism here.
Try mixing with high IQ Thai people like in the FCCT.
Discuss social, economic, political issues. Analyse and debate political issues with Thai people.
There are no facts or evidence to support your statement.
Only unsubstantiated opinion.
Maybe it's the company you keep.
