No, I can't provide concrete sourced examples with a rubric. I'm not writing a paper. These are largely impressions I get from speaking to people in the world, and kind of being taken aback when people have what I think are kind of absurd views. Some, I know from speaking to people, are amplified by YouTube recommendations, and Instagram feedback loops. I don't really think it's a controversial take to say that recommendation algorithms paired with bubbles that match a few different tropes are going to amplify those views.
If you're confused by my rhetoric, that's ok. I'm confused from time to time.
