there is nothing racist .. always bad apples amongst the population. I avoid small landlords in Thailand who only owns 1-2 properties. These lots are the worse.. lack of exposure to the world which made them very difficult to deal with and these will definitely forfeit n never return your rental deposit.
If you can afford international school or decent bilingual schools for your kid(s), I really see no actual traumatic impact but can be a very fun experience for the kid(s). In addition if you are a church goer, there are also lots of teen or children ministries that really have planned activities for bonding n friendships… All in all very international n good exposure for the child or teen.
As an expat I was posted to many countries n my children all enjoyed their stay in each country.
