Seems very vulcan. Works with vulcans and to some extent vulcan wannabees. Words have meaning, and how we express ourselves through our words is how we lead and share knowledge. There is nothing wrong with being honest, but honesty without love and care is brutality.

I see your point, and think one of the merits in OP's argument is precisely what you're saying: words have meaning, and saying something like "I think that X is probably the case" when you're virtually certain that X is the case dilutes the meaning of words.

That said, I think throughout the post OP is mixing different dimensions of communicatiom together in a way that confuses the conversation - namely conciseness, directness, and explicitness - which while often overlapping aren't exactly the same.
