I do not think the Thais want to change the perception. It is not the Thai way, westernised or not. They walk away from it and pretend it doesn't exist. There are threads on this forum with posts from long-time posters, some not farang, one of which I have just read and clearly summarises their view. The issue doesn't need to be put to Thai citizens and it won't be. It is not a perceived problem for them. They can and do deal with it their way.
