ARE CONVERSATIONS A WASTE OF TIME?

I have a dilemma. I'm wondering if it is a waste of time to attempt conversation with my brothers and sisters who abandon truth when it contradicts their world view. I believe that "TRUTH" is the great equalizer for all of humanity no matter your race, gender, or ideology. But if truth is not relied upon universally, then we trade a game where all are bound by the same rules for a game where the rules are changed to achieve victory and the power to change those rules rests with one side and one side only.
