So, they question is, is Truth always a real truth?
Let's say, for instance, your truth is based on science? Have you ever taken in to account that Humans, by nature, have infallible?
They used to think that Smoking was A-OK! Doctors even smoked. Or the fact they used to supply Coke, Arsenic, Heroin, and such as being safe and as a medication?
Facts have a funny way of changing over the years, as does the truth. It is ever evolving as we evolve.
Who are we to decide who's "truth" is real? Why can't everyone have their own truth and just move on with your life without judging them automatically?
