Thinking that the truth is relative is a grave logical error. It is the very height of human arrogance to assume that individual belief has any effect on reality.
Gravity exists, whether anyone chooses to believe in it or not.
God exists, whether anyone choose to acknowledge Him – and the overwhelming evidence of His existence – or not.
Choosing not to accept the truth is every man’s right, being willfully blind to it foolishness.
So don’t be a fool, yo.
