I think you missed my 3rd paragraph (counting the one line).
The problem is the claim doesn't distinguish biased sampling from a biased model. The former is far more likely.
Just ask yourself which is more likely: "my experience is abnormal" or "everyone is experiencing the same thing I am"? In your friend group the latter might be more likely because you're similar locally and culturally. But across the state? Across the country? Across the globe? No, you'd be crazy to think experiences are typical. There's way too many variables at play and even if we were clones we should expect differences.

So no, it doesn't make sense
