Not that my view holds any moderation weight, but for me (and as far as my up/down vote goes) that might've been fine if you'd expanded on it more, exactly what is 'only in rich countries' and how something's specifically different in not-rich countries, i.e. sharing some insight and adding something less low effort to the discussion.
'only in rich countries' on its own just reads like a Reddit-esque meme/jokey dismissal.
That's legitimate. I can agree with that and the downvote. But you realize that I was accused of flame baiting meaning I was accused of making up a statement purely for the purposes of inducing anger.
I would argue that clearly from the evidence in the responses, such a statement (while it did attract downvotes) did not attract flame and therefore was not "flame bait."
