Thus it is not a genuine secular state like a state in western Europe (neither is it necessary to be so because we have not been through the same experience as them, but only taken their type of state as a principle to refer to, even though we are not the same). Whether or not it is written in the constitution, the Thai state is a Buddhist state. This does not mean that we have no prostitutes and drink no liquor, but it does mean that we give Buddhism a status more special than others. The Thai state is neutral between Christianity, Islam, or Hinduism but the Thai state is intentionally and demonstrably biased towards Buddhism.
Whether or not it is written in the constitution that Buddhism is the national religion, Buddhism is undeniably the Thai national religion, and this is openly inscribed in the cultural constitution.
