I said that that way for a reason.

The very fact that my truth is not your truth, means there is more than one truth, does it not?
Even "scientific" truth has been known to be adjusted from time to time.... does "your" definition of "truth" allow for change?
It's a very difficult thing, for some, to realize that just because there are different "truths" does not mean that nothing is stable. The approach does not shake your very foundation of beliefs, imo.
Now, how to differentiate between a separation of truths and the rational/irrational beliefs is another item..
