If that's what you meant, it sounds like a bit if a logical stretch.
I think that stronger statement is questionable for a few reasons:
(1) It ignores the subjective element of your assessment regarding which of Pence's positions are reasonable or not reasonable. I very much doubt everyone on Hacker News would consider all of your strongly held beliefs rational, and vice versa. But that should be the starting point of our discussions, not the end of them.
(2) You gave some examples of Pence's conclusions which you consider absurd, but you didn't give clear evidence that his reasoning processes are flawed that he's "not a person to be reasoned with". For example, if you could point to some discussions where he was unable or unwilling to adhere to basic, simple rules of logic, that would bolster your case.
That's something that I know quite a few of us here in Colorado wonder; my friend who owns an upscale dispensary doesn't think anything will change but I'm not so certain. Esp. if the rumors that Trump approach various Republicans with the idea that as Vice-President they'd be calling all the shots. Mike Pence is kind of a wild-card, I really don't know what his stance is on legal mj but the little I have read doesn't inspire confidence that he'll take a reasonable approach to this.
