1) when I read the offending tweet at the beginning of the article my first thought was "she's making fun of clueless white/rich people traveling abroad." (If you've traveled you may have bumped into this not-uncommon type.) so I think it's reasonable to believe that explanation.

2) I got the impression that this was a personal account, meaning I'd judge it based on what stupid shit I hear people say in bars or other social/personal situations. I know plenty of people who have said way worse things, and continue to.
