Probably because we marry the local prostitutes. Drunken fights over the prostitutes is not a good look either.
We see it as saving the woman, her children and extended poverty, but most Thais see us as stooges.
I think it is fair to say that the prostitutes and their families cherish us, probably don’t respect us, but to expect the general population to respect us is probably asking a bit much.
Back home in the UK we are rioting over the unwanted immigrants and it is also a decisive issue in the USA with their southern border and other parts of Europe also.
If we are living here full time I don’t think it is too much to contribute and pay a bit of tax. They do not have high tax rates anyway. Same as we would expect immigrants to contribute back in the UK instead of just asking for handouts.
