TL;DR version; Yet another butthurt expat rant
This rant is stunningly similar to the type of rants that expats write when they are butthurt that where ever they emigrated to didn't treat them like a the best thing since sliced bread. "They're all racists, 300 or so years ago they did this and that, their way of thinking isn't right"
If it was so bad why did you hang around for so long? Bugger off and don't come back.
 because it's different to my way of thinking, which is automatically the best way of thinking.
