Fight the sunlight? What the hell do you even mean?! I don't have a 24-hour sleeping schedule naturally. I can force myself into it, but I'll feel miserable because I have to fight my own body to not "fight the sunlight". Some people start naturally getting drowsy in the evening every day, yes, sure. Good for them. I'm not one of those people.

So I'm very much with the author here and I might actually try 28-hour days because what I have for the last 10 years is a mess.

Are you not getting much sunlight? I can understand the reaction to being told something that doesn’t match your experience. But. The link between sunlight and sleep for most life on earth is pretty well established science, and has a name: Circadian Rhythm.

Have you ever tried camping for a week? My sleep tends to drift when I’m working indoors a lot, up late at night a lot, during winter, etc. But if I spend multiple days outside, it starts to align with sunrise almost immediately.

Both of these links say that Circadian Rhythms tend to drift and be longer than a day on average in the absence of sunlight.

I'm not getting much sunlight. Especially now. But I was getting plenty when I lived in Dubai for several months. Didn't change anything much, my sleeping schedule was still slipping. So no, your theory is wrong.

Non-24-hour sleep/wake disorder is not something one can fix like this. I would if I could. I've had this problem since my late teens.

Fair enough, but it’s called a disorder for a reason. It’s still reasonable for people to talk about the known link between sun and sleep by default, and not assume something’s wrong with you, right? It sounds like you were already aware what it meant before asking?

I think they mean that light exposure has been causally linked to wakefulness, which I'm sure is a statistical thing and not an absolute thing, meaning your experience is still valid even though it's different. Your indignation made me chuckle though, I appreciate the tone.
