If what you're trying to get at is that whereas it is very important to unlearn the lies and exaggerations one was told about a country, that people also need to avoid replacing these lies with an overly simplistic and uncritical understanding of that same country, and that the current social media landscape makes it very difficult for many people to have the necessary nuance to avoid this pitfall... Then I would agree with you, but I'd also tell you that mentioning the eugenicists' favorite way of measuring "intelligence" is a very bad way of phrasing this idea, and that your standards of what counts as "circle-jerking" about a country are probably not nearly as inviting of nuance as you'd think.
