Lady Gaga did not insult the culture, the heritage, the language, or the religions of Thailand. She didn't give someone a noogie. She merely stated that she tweeted that she may or may not have bought a fake Rolex watch in an area known for knockoffs?
If this is what enrages Thailand, then Thailand is a nation of easily enraged people. Perhaps they've had enough concerts and Western culture. Oh, and definitely don't explain Etsy to them, either. Their poor, never-to-be-touched heads might explode.
