I never claimed that truth has to conform to reality. In fact, throughout history "truth" has quite often been in direct conflict with reality. Whenever science has come into conflict with those in control, truth is whatever those in control declare, and reality suffers.Because "truth" is only what we believe to be reality, not necessarily reality itself.
A good example of this is the current global warming debate. The reality is that the planet is growing warmer, slowly but surely. The "truth" which is being propagated by certain people is that it's all mankind's fault, that we are responsible. Yet evidence shows that the Earth has undergone other periods of warming and cooling which rival the current period, before man ever became "civilized" enough to have a significant effect. So how much of an effect are we really having? Nobody knows for sure, but those with an agenda, one way or the other, will tell you the "truth" as they declare it to be.
