The problem is that in these conversations I'm describing the level of power the game gives to the DM, not how I describe my play. People, despite my saying in these conversations and in other threads that I run my game very differently(with examples), want to ascribe those words to me as if I'm some power hungry madman DMing so I can put it to the players.
I need a different way to say it.
There is this idea in media that you can increase clicks or viewership by invoking emotions. It's why news coverage is overwhelmingly negative. Outrage sells. Negativity and other powerful emotions increase engagement. You can manipulate people with this pretty easily. You see this in pets, doesn't matter what you say, only how you say it. Humans aren't that different.
So your own passion and desire to express your point succinctly actually works against you here. You are using words that invoke an emotion, and it's normal to associate emotion with it's source. If someone makes you feel bad, you think of them as making you feel bad. Crazy idea right? Simple tone and word choice can do this without changing the content of what is said. Ever hear "You are lecturing me," in arguments between couples? That is a delivery issue and is rarely content driven. Most arguments are, the difference between "I understand" and "I hear you" when in a heated discussion is deceptively big.
You can get your message across and not get the reaction you describe by using neutral language in making the point. Such as the "DM being given creative control over the world and broad leeway within the rules." I'm stating the same thing, I'm just not engaging in hyperbole and dramatic language. Saying "the DM has a lot of leeway to bend the rules" will invoke a different response to "The DM has absolute power over the rules."
You can look at it another way. In a couple online ads for a D&D games you have two DMs running two games. Both have restrictions on their games as far as available races go. How they phrase that restriction has an impact. Saying races are banned is less appealing than listing the races that are allowed, as a simple example. Telling players, in the ad, that it's "your way or the highway" is going to garner a more negative reaction than saying "These restrictions are here for worldbuilding reasons and I'd like people to oblige."
Going further into the discussion at hand, you can address the players differently too. Instead of saying the "players have no power" you could say "the players power is social" Or comment that "Outside of the game everyone is equal." Both are better than saying "players have no power but to leave the game" or "DMs have ultimate power over the game." In the latter you just dodge the issue, and point out the positive for the other side. Players have immense power outside of the in-game actions. Focusing on the positives for the other side, while being neutral in your delivery will just cause less hostile reactions. It's similar to tone of voice, speaking loudly is often perceived as more hostile than speaking softly.
Avoiding words like "you" when talking about some belief, and instead not directing it at anyone, is useful as well. An example might be "There is a belief that DMs are broadly ruining games but that doesn't match the data" is much better than saying "You believe that all DMs are tyrants even though you know it's false." It lacks the confrontation and is more neutral in it's word choice. The response will be to the assertion that it doesnt match the data, not to your philosophy on DMing.
Instead of looking for a term, just explain what that term means in a neutral way and dont worry about the term itself. You dont have to describe the DMs power, you can talk about the role. Use your word choice to cultivate the type of response you want.
Hope that helps. It's really hard to explain through text.
EDIT: Another example is "Can I help?" versus "What's wrong?" The former will get better responses in most cases.
