A few points:
1. There IS.. an objective reality, wrt 'science'. Scientific methodology is based on order, empiricism, and the immutable laws of nature.
2. This scientific knowledge is 'knowable', and is factual, whether it is believed, understood, or not.
3. It is possible, in the realm of scientific inquiry, for someone to be 'right', and someone else to be 'wrong', on a specific point of truth.
4. Right and wrong, wrt scientific facts, are not pejoratives or propaganda memes... just reflections of reality.
5. Someone can be 'right', scientifically, and be a rude, intemperate a$$. And, someone can be wrong, empirically, and be the nicest person, ever. Truth is not dependent on personality.
6. Debating 'facts & science!' is an empirical, logical progression, not related to the personality of the debater.
7. Obsessing over the personality of the 'debater', is an ad hom deflection, in a rational, empirical debate.
8. The quest for Truth is not always pleasant, fun, or soothing. Uncomfortable truths upset our beliefs and biases.
“To love truth for truth's sake is the principal part of human perfection in this world, and the seed-plot of all other virtues.” ~John Locke
