Your points here are quite shocking. You've no idea how or why the author of the blog post ended up in the country they were in in the position they were in; it's not stated in the blog post or here in the author's comments in this discussion.

This apparent need to push the discussion away from the issue being presented and instead engage in some moral grandstanding on an irrelevant point comes across as suspect.

If you were presented with an example of a walled garden causing distress to someone in a nice, white Western country, you'd presumably rush forward with your sympathy, would you?
