The following requires some real thought. There is lots of discussion about truth, fake news, and the motives of trump supporters. .
The word truth evolved from troth, as in I pledge thee my troth. Troth is a word about the relations among people – feeling. Truth is more about our relationship with physical things -fact.
The politics of the Trump supports s more on the line of faith than of fact. Faith with Trump whom they see as having faith with their sense of community and willing to fight for them Think of te way the fans cheer at high shcool football games (“Kill em Chico”)
Understanding this difference helps us -and we need help – understand what motivates those who continue their Trump support.
This understanding would lead us to a politics which is true in both senses and a better understanding of how we got into this divisive bifurcation. I think the division is deep in our cultural past and plays out now as the democrats are seen as the party that used to be for labor but now is the party of the professionals and the Trump supports are the community of those whose culture is losing out to abstract forces.
The following from th ever useful https://www.etymonline.com/search?q=truth
Old English triewð (West Saxon), treowð (Mercian) “faith, faithfulness, fidelity, loyalty; veracity, quality of being true; pledge, covenant,” from Germanic abstract noun *treuwitho, from Proto-Germanic treuwaz “having or characterized by good faith,” from PIE *drew-o-, a suffixed form of the root *deru- “be firm, solid, steadfast.” With Germanic abstract noun suffix *-itho (see -th(2)).
Sense of “something that is true” is first recorded mid-14c. Meaning “accuracy, correctness” is from 1560s. English and most other IE languages do not have a primary verb for “speak the truth,” as a contrast to lie (v.). Truth squad in U.S. political sense first attested in the 1952 U.S. presidential election campaign.
troth (n.)“truth, verity,” late 12c., from a phonetic variant of Old English treowð “faithfulness, veracity, truth;” see truth, which is a doublet of this word. Restricted to Midlands and Northern England dialect after 16c., and to certain archaic phrases (such as plight one’s troth). Also see betroth.
