I think the situation today is different because the "bad" content can spread much more rapidly and broadly than it could before. Back in the day, you could judge the authority and value of the content you were getting because you knew the source, and sources that produced content which most people judged poorly couldn't spread their content much beyond a small group of core believers. But today this content spreads without clear links back to its source, which makes it hard to judge, and it spreads so widely and rapidly that there's no opportunity to discredit it before the next bit of content comes zooming by.

This "bad" content is coming from everywhere, too. Recently, most of the factually-inaccurate content has been coming from, or has been in support of, the alt-right. But in the past a lot came from the far-left as well, and there's always inflammatory agenda-driven propagandist content come from extremist groups of all types. Every group with an agenda to push can easily slide from fact-based content to exaggerated content to outright false content in an attempt to be heard, and that's much easier today than it ever used to be.

Education would help, but only if the sources of the content people are seeing can be identified and judged by them. I have an even more difficult solution: integrity, self-control, and professional restraint on the part of the content producers. I think we lost that when news became entertainment, and I have little hope that we'll ever get it back.
