Some people object to being reminded of "obvious" truths, such as are found in proverbs: "A house is turned into a home one kind word at a time." But consider. First, we live in such an overwhelming information tsunami that unless we repeat common truths, they will sink into oblivion under the wash of everything else.
And often that everything else includes misinformation, disinformation, lies, half truths, urban legends, myths, conspiracy theories, ideological fabrications, spin doctor treatments, invented narratives, and misunderstandings, not to mention simple errors, superfluities, and data smog.
In a word, lies are repeated endlessly and constantly. Lies are shouted from the housetops and pronounced solemnly by pundits and academics with many letters after their names. Lies drone on and on--wasn't it Hitler himself who said something to the effect that a lie repeated often enough will be believed?
So, if we don't repeat truth, it has no possibility of overcoming the lies. Error will reign and people will congratulate each other that "the controversy has finally been settled" because no one now opposes the ever-repeated wrong conclusion.
