Your comment is a textbook example of collective blame, which is both logically and ethically flawed. Criminal acts committed by a small number of individuals do not define an entire population or industry.
FYI, in case you haven't noticed, Thailand’s tourism sector employs millions of law‑abiding citizens, many of whom depend on it for basic survival. Studies on stereotyping and group attribution error consistently show that conflating isolated incidents with the behavior of an entire demographic fosters prejudice and undermines constructive solutions.
Or, is this somehow your opinion on Thais in general? If yes, why are you here?
