Are you saying that internet commenters have a monolith "worldview" that could be referred to as "the worldview of a few"? I'm not saying you're saying this, but that's what I read.
No. I'm saying that each person has a worldview, which is the aggregate of their life experience. If a small set of people drive most discussions, then the discussions are (mostly) a reflection of their perspective only. Maybe these perspectives are diverse enough, but it's hard to know.
