I'm not talking about when I have opinions - I'm talking about demonstrable evidence, like DNA for evolution, geological evidence that the planet is more than 6k years old, and so on. No "belief" involved - these ARE facts, not opinions, and are not subject to disbelief - ***unless you are willing to deny reality*** to protect your beliefs.
I ask, why should I respect that denial? Where is the right of the faithful to be ignorant of facts?
