I have very much enjoyed this story but as an American it does jump out at me obviously that it wasn't written by an American. Normally this wouldn't bother me as it's a fictional story and very hot but it's the fact that the author initially framed it as "a true story" that I think has motivated people to comment on it. I think it's perfectly valid to offer constructive critique as feedback to a story especially one posted on a forum like this, if the author didn't want any feedback they could post this on another platform like nifty that doesn't allow for comments and discussion.
To everyone aggressively responding to those comments instead of ignoring them or just saying "yeah but it's just a story", you're just making this a bigger deal than it otherwise would be!
