Actually it is not accepted by all in Thailand.
“ Buddhism mentions kathoeys as the third gender, but that doesn’t stop monks from telling ladyboys who they should be. ‘We can’t change them all’ said one monk in the interview for The Telegraph‘but we can control their behaviour and show them that they were born men and not women’. Some monasteries offer special programmes, where parents can enrol their kids and where the young ones are taught how to be men again.
Kathoeys are treated as second class citizens in Thailand. They are not bullied, but their role is mainly to entertain others. They can be stylists, make up artists, dancers in one of the cabarets, but getting a well paid job
might prove very difficult”
