Hi,
While I agree that many if not all people confuse truth with what they believe is true, this is the art of deception. It is the world of today where perceived truth is more important than actual truth. It is mind control by creating and controlling public opinion through misinformation or fake facts.
But I think when you say truth, most if not all people would agree that they're referring to objective truth. This is of course based on legitimate facts which can be very hard to confirm in our present greedy, lying, false flag world.
I think this is important so we don't confuse the meaning of truth since this is the type of thing Orwell spoke about in 1984 with doublespeak and newspeak. So for me and I hope others, there is only one truth and it is objective truth backed up with legitimate, provable facts. If you're wrong then you don't have it and need to do more checking.
