The parent made a few direct statements that seemed pretty clear so I’m not sure what you’re looking for.
It wasn’t me so I _could_ be wrong but I read this:
1. Twitter has more right wing content than it did before Musk.
2. It’s generally not extreme.
3. It’s good to have different views.
Yes, those are generalizations but I would think they’re clear and concrete enough to agree or disagree with. They’re generalizations so specific examples really wouldn’t contribute to the conversation either. I don’t get what sort of clarification you’re looking for. Maybe some sort of formal statistical analysis?
Of course, if you’re just not interested in generalizing about Twitter that’s fine but this whole article isn’t for you then.
