Dude, relax. Can you post proof to the contrary? If you cannot, then your position is indeed weakened. In any case, those links are in line with my own studies at four colleges and universities in Norway. If you can document something that disproves those links, I'd be quite happy to see them! :)

I’m doubting what parent says, why would I need to disprove if they’re going by handwavy articles and personal anecdata?

I think we've provided some evidence that suggests there at least might be a problem.

Publishing a rigorous scientific paper saying "well look, here's the problem" is going to be difficult, given the issues such a paper would address. It could be career suicide if handled indelicately.

Given that we have weak evidence that there is a problem, the burden of proof is now on you to provide stronger evidence that there isn't a problem, unless we have a strong prior for there not being a problem or something.

Applying higher standards to things you disagree with is a great way to end up biased. If you require a well reviewed research paper showing that there is a problem, you should also require a similar paper showing you there isn't a problem.

At the very least trying to provide a counter viewpoint to the evidence you've already being presented with would be polite.
