I've previously written about lèse majesté in terms of how it is implemented.
A recent issue of The Economist carried an in-depth article about the Thai royal family and succession issues. Consequently, Bangkok Post reported that The Economist would not be distributing that issue in Thailand due to lèse majesté laws.
Within the readership of The Economist, it has generated a debate, with the magazine suggesting that "[w]e hold that Thailand’s lèse-majesté laws should be lifted. They harm the country itself; on those grounds they should be removed."
Of course, given that nobody within Thailand can have such a debate, the comment may fall on deaf ears.
