So is that your response to OP's question then? They're wrong about seemingly everyone agreeing because they are mistaking respect for agreement? They mention wanting to see dissenting opinions respectfully, so I don't think that's the case. They are talking about how the majority seems to be on the same wavelength, not that there is a lack of polarization. Again it seems like you have an answer to a question OP didn't ask ("Why aren't there more trolls and tribalism on the fediverse?") because that's what you want to talk about instead.
