I guess you could say I am emotionally attached to objectivity and the truth. A truth doesn't always exist but sometimes it does and when it does it reasons we should all be in agreement with it because opposing positions can't both be right on a matter of truth.
So in the case of Dr. Z. Dogg, I would speak up if someone said something demonstrably false against him. And I would do this whether I loved him or hated him. If someone said Hitler ate babies I would point out that there is no evidence he hates babies but not because I defend Hitler rather because I try to defend truth. So take a coworker I might hate and not get along with at all, I still wont exaggerate negatives about them.
I do enjoy a good debate with points and counter points even on topics I don't have a stance on. I appreciate a well formed counter argument even if it is from a position I disagree with. Sometimes speak to sway others on a topic and sometimes I do it just so the discussion is well informed and full of context. We don't necessarily have to come to the same conclusion but it is still better off to have an fuller and more accurate understanding of the opposing viewpoint and sometimes a thought experiment accomplishes that
I hope that adds a bit of light to my discussion style.
It's a fact (as in "true") that you and I can both be right at the same time while having different opinions on what the truth is.
Let's say you have several well-documented studies, clinical trials and testimonials that a new, cheaper, more environmentally safe soap exists. So you swap out all the old soap dispensers and install the new ones. You have all the data on you side to support that decision.
However, I also have studies showing that 5% of the participants have allergic reactions, can't stand the smell or simply prefer the old soap. I also have evidence from the EPA that shows any benefit to the environment caused by using the soap itself end is more than negated by the cost of production to handle contaminants/byproducts safely with special machinery that use hard-to-mine rare elements.
So, while your conclusion is right based on the information you think is relevant, I am also right in rejecting the new soap since the old one had no negative studies affecting a portion of the population no matter how small.
If 5% of the soap users are not happy, whereas 100% were happy before, was it "more right" to try and save money over keeping all the users happy?
The answer lies in whether you have the money to continue using the old soap versus how disgruntled the 5% will become (resignations, lower employee productivity, ...).
It's almost a problem in quantitative analysis and optimal solutions. You have to include all constraints on every possible solution before you can determine the optimal solution. That means that it's possible for there to be 2 optimal solutions depending on the weights assigned to the constraints. The constraints can represent many things, including the need to cause no more resistance over the soap change than existed before. That causes my solution to be right. If the constraint says the cost is required to be X% lower than the previous soap, that causes your solution to be right, If the dollar cost and the resistance factors are equal, then those 2 constraints are not going to determine which solution has more merit. If all other things are equal, then both are correct, but they achieve different objectives based on priorities.
