Was it neglect? Murder? Suicide? Or was it all an illusion to begin with?
In the near complete absence of data or context, my opinion is, “Yes.â€
One comment relative to modern usage of the term as an argumentative proof is that claiming the turf of common sense is self negating. The reason being that if there is an argument being had about a subject, the sense is, by definition, not common. This might fit the illusion category.
I do think electronic communication has enhanced the untempered frequency and degree of the appearance of uncommon sense, so there’s that. Could be an example of neglect.
And the viral opportunity to spread uncommon sense is extraordinary. Perhaps that fits suicide.
And, there is an industry specializing in the trade of uncommon sense as an intentional endeavor. That would be murder.
