I don't believe there is a "Truth", with a capital T. There is only "truth" that is supported by facts as they are currently understood. By observing and experimenting we are continually refining out estimation of the truth, approaching it in a asymptotic manner. All truth is preliminary, subject to the results of the next experiment.
As to why people can't seem to agree on the truth I believe it is a result of our different prejudices and "beliefs" (things we accept as fact with no actual evidence). People are unwilling to critically examine their own conclusions for a variety of reasons: pride, fear, peer pressure, etc. People hate to be wrong. Honestly seeking truth is a character-building experience.
I believe that there is Truth (with a capital T), but that Absolute Truth is inaccessible to us, and if we found it, we'd never know for sure. Truth nevertheless has consequences. Climate change will be a disaster--or it won't. One of two people will win the November presidential election in the United States. We can't say with certainty that it will be Trump or Hillary. It conceivably be could be Johnson or Stein. I'm willing to bet that it won't be the latter two, although I'd grudgingly have to admit I could be wrong (but I doubt it). I'm not willing to bet on whether it will be Trump or Hillary, but I am willing to bet that if it's Trump, he won't make America Great again (whatever that means). These are matters of judgment, based on information, personal experience,analytical skills and intuition. I think a person with more information, analytical skills, relevant life experiences and intuitive abilities is likely to make better predictions than a person with less of these traits. But the predictions won't be completely reliable, because we are all fallible. Nobody knows it all. There's always a faster gun in the West. Truth is in that sense always relative, And then there are values--shoulds and shouldn'ts. I think those trade deals Trump and Hilary are attacking will create jobs in other parts of the world and help American consumers in the long run, but I can understand why blue collar factory voters feel threatened by them--since in the long run (as Lord Keynes put it) we'll all be dead. Bentham and Sam Harris have tried to get scientific about values in terms of human wants and needs, but their hedonistic assumptions have been rejected by many ethicists. That part of Truth I think will never be reached by reason alone.
What bothers me about the way the thread is framed is the suggestion that everyone's "truths" are on the same plane. This is a useful perspective for avoiding violence at social gatherings, where Trump supporters, Hillary supporters, Johnson supporters, and Stein supporters may be gathered in the same room. But I'm afraid they all can't be right, and I think information, logic, experience and intuition can help us in predicting who is. It does make sense to argue or discuss the candidates' positions. And even in the values area, I'm willing to say that some people have rotten values: the selfish, mean-spirited types, racists, etc. The notion that we make our own reality has been carried to ludicrous and dangerous lengths by "New Thought" followers. I dated a girl from the Unity Church once, who thought we must always be careful not to think bad thoughts because they'll come true. We were walking near a bad neighborhood once and I told her we needed to turn back because we might get mugged. She was horrified that I'd think such a thing because I might make it happen! Gimmie a break!
