Strangely your comment holds true in areas where community means you get many different perspectives.
In my experience (growing up in the south), it's "strong-knit" communities that are doing the most harm in perpetuating mistaken beliefs or amplifying anger.
What's especially weird is that this holds true when some communities' economic status is considerably better than the majority of the country!
There's a momentum behind beliefs that get culturally amplified. And it's hard to disagree with people when you don't have immediate examples to compare and contrast. Or worse, when your very livelihood gets threatened for going against the flow.
My own experience (given the above) is why I'm eternally grateful for the unfiltered internet I had when I was growing up. I wouldn't be half the person I am today without the many varied perspectives that I had access to per-social media bubbles.
