I, too, old this belief, but it's kind of hard when the "new culture" is overwhelmed with a sense of entitlement to "be heard". Everyone thinks their individual opinions should be able to be shared whenever they feel the need to be validated, and that everyone must hear their opinion in that moment, regardless of how controversial it may be. And if you try to stifle their attempt or even mildly disagree, then you are the bad person. Couth and tactfulness have given way to entitlement and postmodernism in the modern work culture.
