Actually, I left it out as it is irrelevant (IMO), due to the fact that you can never be sure that you aren't going to offend someone. Even in a "localised discussion", talking with close Thai friends who you feel you know and trust, topics of this nature can completely transform people. It's just the way people are in countries such as Thailand.
I thought you would know that, and the fact that you apparently don't prompted my comment. No obtuseness or intellectual dishonesty here. (Not my style.)
