I was pointing out that the reason people started arguing with you is because you said that they're posted on the edge of municipalities, and they said that they've never seen them visibly posted anywhere that wasn't a highway and asked for specific places where you've seen this hapoen. You then switched to arguing that they didn't believe that minimum speed limits exist at all.

You're straw-manning.

But, since you accused me of making the same argument, for your information, I used to drive for a living. Everywhere obviously has minimum speed limits, but where I live, they're only posted on specific roads where they differ from the norm. Most people could probably go their entire lives around here without ever seeing one that wasn't posted on a highway alongside the signs saying that it's illegal to ride a horse down the highway. We don't have signs that say, "Welcome to the town of Smithston, minimum speed limit is 15mph." The minimum speed limit is statewide, except in cases where a town deems it necessary, which is usually specific roads, not an entire municipality.
