You make a good point that not all parts of the claim are false, yet, there is still some partial truth to this claim. Studies do show masks can be effective, even if they aren’t perfect in every situation—especially since not everyone has access to the best masks. But they were the best option we had at the time. As for school closures, it’s true that they negatively impacted kids’ mental health and well-being, and some groups were hit harder than others. That said, this claim seems more like one person’s opinion than a solid, well-supported fact. It’s important to stick to credible sources when talking about topics like this and to do proper research when making claims that are in regards to health, especially considering there are plenty of scientific research studies out there.
