Looking at the poll, there were only a thousand "registered voters" that were meant to be a representative population of the America, which I'm gonna give a hard pass.

tl;dr his evidence, even if we assume the issues you bring up are significant, outweighs your lack of any, so I am leaning in his favor
The evidence here is sufficiently poor to provide minimal value. Poorly collected data can often be worse than no data, as it can mislead you.
No it doesn't. It depends on the fact that I don't know the opinions of other people at all. But I can infer that the selection biases of "registered voters" (which I think is a far bigger confounding factor than anyone is giving it credit for), and self-selection make it too difficult to extrapolate to the population of US citizens.
On the no-harm side, I see nothing.
On the harm side, I see a study about which someone has raised some concerns.
I understand you have concerns about the study design, but I'm not confident that they affect the outcome in such a way that the study provided zero evidence for Facebook being viewed as harmful.
Is there a study which doesn't run into the same concerns which says the opposite of this one?
I personally also think Facebook is harmful.
