bkkmfj...I have to be honest with you...I'm having a very hard time digesting what you just said.
In all my years in Thailand I have never once heard a Thai make a statement like the one quoted above. I'm not calling you a liar, but would just like to emphasize the fact that the overwhelming majority of Thais - regardless if they're gay or srt8, would consider this type of statement to be in very poor taste, insulting, and confrontational. In short "Bad Karma".
Contrary to the opinions that you and Latin seem to share, I see gays as being widely accepted in Thai society - with little or no stigma's attached. Those working in the sex-trade industry have a different set of circumstances to work around for obvious reasons. Face-saving for the family being one of them. Regardless of how open Thai society is towards gays - prostitution is frowned upon in Buddhism big-time - but viewed by many Thais as a necessary evil especially when it deals with impoverished families.
I wonder sometimes if farang don't have the impression that all the gays in Thailand are prostitutes, when in reality gays who work in this profession represent a very small percentage of the total gay community. Maybe they should drag themselves off the bar stools in BKK and PTY sometime and visit the real Thailand.
Based on everything I've seen and experienced over the years, gays, including trans, toms, bi's, ladyboys, etc. are fully integrated and accepted in Thai society.
Regardless if you're interacting with with hi-so's, low-so's, mid-so's, or even a few soso's in Thailand, I think you'll find them all to be humble and friendly. It's just the Thai "Way". The hi-so guy you mentioned in your post would definitely be the exception.
