Are dissonances and group agreement compatible?

How do we engage with these dissonances or alterities in our expectations?
How do we, as facilitators and pedagogues, resist a more utilitarian urge to maximize what might appear to be group agreement in the space, at the cost of the outliers? Might we, as guides through these spaces, have an obligation to address these outliers in these moments of tension?
And, what does this teach us about our facilitative practice and how we approach difference?
