You have confused truth with your perception of it -- conflating objective truth with subjective perception.My question would be - whose truth?
Truth is subject to whomever is thinking on it.
There is only one Truth. It is attitude, belief, education (or lack thereof), and other factors that affect our perceptions of the Truth.
Example: A certain object reflects light most strongly in the 625–740 nanometer wavelength range. A person with normal vision will perceive this hue as 'red'. A person with color-blindness would perceive this hue as a shade of grey instead, and their perception does not change the fact that the object reflects light most strongly in the 625–740 nanometer wavelength range.
Now, if you* want to talk about philosophy, politics, and/or religion -- concepts and ideologies -- then one person's 'truth' is another person's 'fallacy', 'delusion', or 'blasphemy/heresy'.
Believe if you* will that the Flying Spaghetti Monster delivers candy to good boys and girls from the back of their Invisible Pink Unicorn -- that's your* right. I will believe that the universe instead operates within the parameters determined by scientists through the Scientific Method, and that these parameters are constant throughout the universe, and regardless of an observer's frame of reference.
