In 20 years of living in Thailand, including lots of time in Bangkok and Pattaya, no Thai has ever provoked or threatened me. In saying that lots of them have tried to jump queues in front of me, both male and female and I approached them in a normal way, told them and pointed to the back of the queue, and every time bar none they have done so.
Apart from their road behaviour, I have found the average Thai to be decent, honest and non confrontational.
