Fio you wouldn't believe the things I've heard discussed by groups of Thais sitting around drinking in their homes, in bars, in card games, here in Thailand and even among groups of Thais who have settled in Australia. The gals who are in the industry or have been in the industry feel no degradation or humiliation, they boast of the number of guys they have serviced and the weird acts they can perform. I've heard it countless times. As I said hard for some to believe. And no I’ve never been hell bent on humiliating a ping-pong lady with personal questions - That was purely given as a hypothetical example.
But Fio, there are many different points of view around. I can't understand why you get aggressive whenever somebody has a viewpoint that differs from your own, and you seem hell bent on tearing him or her to pieces.
