Of course, as with any hot meme, it gets a semantic makeover in the course of widening adoption, but if you're looking for an answer to the question of whether someone who uses "normie" unironically, especially in a context outside Reddit or a *chan, merits taking seriously...well, at the very least, I think it's reasonable to interpret that at least as a strong clue that the user isn't in the habit of thoroughly considering his utterances before emitting them.

Things need to be straightforward & familiar for normies (eg. Pokemon Go vs Ingress) and you can't expect to hold a high level conversation with a good chunk of them, whether that be about mathematics, policy (so much circular logic), reality (citations & sources are not a thing many normies are willing to use), etc.

That being said, its not all bad, just set expectations accordingly, just like you would going on HN. I do not expect the average HN reader to understand much about traffic dynamics and the minimal efficiency gains that may come with self driving cars, or the sheer volume of people a moderate sized light rail network can move in a timely manner, so I set my expectations very low.

Its like talking to a Microsoftie about rail or self driving cars, there is a lack of knowledge (the fact that Amtrak runs trains from Vancouver to Seattle to Portland and is paying BNSF to make the route more reliable) and a conceptual barrier that I do not expect them to rapidly grasp (bullet trains need dead straight rights of way, no exceptions).

Edit: Apparently I can't reply to you, nevertheless I picked up normie as a term in meatspace, and while it might not meet your sensibilities, I do not see a more accurate term, and I'm not here to intimately know & defend your sensibilities. Same goes for asking me or telling me your pronoun, great for you, I give not a single shit, use what you want and cut to the chase.
