Nothing wrong with her English abilities, There are few, if any, on here who could translate her OP into Thai, although if her canadian husband actually proofread it , I can only assume he's a french speaker.
Thailand is by nature a pretty inward looking country, and I kind of get that, they do need some protection from foreign "big business" moving in and controlling things, The more "liberal minded" amongst us, are , in my opinion, a little too quick to hurl words like "Xenophobic" and "Racist" into discussions of this nature' when perhaps "Patriotic" or "Protectionist" or even just "selfish" if you must, would suffice.
I'm generally quite happy with the "Thailand is for the Thais" line of thought, and to be honest I'm also more than a little bit jealous of the sense of national Identity that they all share! Something that my home country (the UK) and many western countries, lost a long time ago, To the extent that many of our population and many politicians seem to actually hate our culture, and seek to destroy it ! The end result ? Well, open displays of patriotism are generally frowned upon, Aspects of Christianity are "problematic" The destruction of historical statues goes virtually unpunished, Even talk of changing the words of the National anthem, for fear of "offending" foreigners , to quote just a few examples .and bizarrely all instigated by UK nationals ! Is it any wonder that many choose to live here
She is at least on the right side of the fence when it comes to keeping weed off the narcotics list, and if she is seeking a bit of a name for herself then why not ? It's no different than Chuwit looking for a bit of fame by ostensibly joining the opposing camp very recently
