Men, women and tgs are so confrontational with each other in the West. Everyone seems to act in an entitled manner. In Asia we have a rule of respect and non confrontational attitude. Very much to do with buddhist philosophy to life of " live and let live with respect and do no harm to others". A philosophy that is ingrained in our daily life.
We hold seminars for Thai tgs travelling in Asia and the West. Thailand rule is simple, of you are in female mode use the female if in male mode use male. It would be unacceptable for a drag queen with a beard to use the female toilet.
In other countries in Asia. If you still have a penis and do not pass as a female then use the mens. Be respectful of other and dont seek to offend them. Most countries in Asia define the use of bathrooms by penis or non penis by law.
We advise those travelling to the West, especially those that have a penis and do NOT pass to not use the female bathrooms and to dress androgenously. Thus, using the male bathroom, when needed, is non confrontational. The Thais tgs, while accepted by society, are not given female ids. You cannot change your gender on legal documents. Thus travelling to the USA they could face legal issues, if they have a problem with someone in the bathroom.
