There is no shame to be had in being direct to a fault. Being so forward and explicit to the point people might think their feelings hurt really is better for everyone. There exists no room to be misinterpreted or misunderstood when you emphasize, consistently throughout I might add and not just in one specific case, that you are making an executive decision. Traditionally, I will negotiate with players or hear them out, but make a decision either way that favors the overall goal of what I am doing and the game I am running. Furthermore, coming predominantly from a tabletop realm, I will always side with the player who has the rules citation and defer to the official ruling on it; when there exists no such rule, I create a universal rule everyone is held to. Exceptions might exist in extreme circumstances, specific beats general, but those are few and far between with me.

It is transparency at its finest in this approach. No less, I take it even in the games I am a participant in. I will be as blunt with you as I can be to show exactly what I have in mind and why. I absolutely disdain politicking and playing instances of "Mother may I?". Roleplays are most often, at least here, among a group of people and with that group they wish to be roleplaying rather than arguing. Wasting more time on that puts everyone worse off.

As for being intolerant and trying to be right, they do have a point in my specific case. Either you are right or you are not right is my perception of things. Why? If I am the Game Master, how else could I be wrong unless I violated one of my own rulings? And with intolerance, either something does or does not fit into the world and work I am building for players to then build off of. Simple, or so I see it. Shades of grey are unneeded in something as simple and less than nuanced as a roleplay topic.
