The problem I see with the vast majority of hypotheticals on this thread is they they all seem to paint the DM as a jerk who makes random decisions without a care in the world about what their players think.Are you saying that you don't use hypotheticals to suss out the truth or falsity of issues/rules/arguments? Unless I understand you wrong you're basically saying that you don't accept any argument by analogy, ever.
I've had bad DMs. They exist. I just get tired of being lumped in with every bad behavior because I have a clear vision of my campaign world that only includes a limited number of races.
