Frustrating, but true. I was recently asked at work to stop adding statements on certainty, to be more concise. I suppose they were in essence delegating the decision of whether something matters to me. That's in some ways a reasonable request, because if I make a nuanced presentation, the audience doesn't have the education/knowledge to evaluate the nuances.
