And yet that page works better on my phone than many mobile first designs.

Take a gander at home; there's lots of interesting stuff there:

https://midimagic.sgc-hosting.com/index.htm

Some fair points, but also a lot of "old person complains about new things and young people".

Yes, I submitted the page because I thought it would give people a good laugh.

But there's also something we can learn from this page: Specifically, what is a bad attitude to have towards change? What are the kinds of changes we need to anticipate?

And even though it's okay to decide that we aren't going to support some new technology, how we deliver the message helps our credibility. (He claims to be a computer science.) If this guy was using a CMS, he probably wouldn't need to worry about supporting mobile browsers. I think if all he said was, "I like making my HTML by hand and I don't have time to rewrite it all," his tone wouldn't be as insulting.

That site sure is something...

Looks like he's done some interesting stuff, but: Some of his views I can't stand: No gun control; No freedom from religion; Contradictory views like "Government must not adopt policies that are offensive to any religion" - how does that work where two all options are offensive to some religion?

Sounds like a conservative kook.

Yeah I submitted that site before I poked around and looked at his political and religious views.

I try to respect everyone's opinion regarding those matters, but it's really hard when there are people who deal in absolutes and can't respect other peoples' opinions.

Unfortunately, mixing politics and religion is a poor choice. I don't think God chooses sides between republicans and democrats, or whatever parties happen to be common in your country or time that you exist.

Sadly mixing politics and religion is highly effective because it turns voting for a particular side into a "religious war" in which very little thought is applied as to if the candidate is actually reflective of your values. (See Trump, Republicans, and evangelicals)

This site doesn't need mobile friendly pages. It's literally just raw text with minimal formatting.

It's about as close you'll see to just plain hypertext nowadays.

There's really no point in saying it doesn't need mobile friendly layouts. It also doesn't need vr support or gpu rendering.

The point of mobile layouts isn't that you must enforce them on every dev to support every mobile browser. It's that if your site needs different functionality for mobile, you can do that.

This dev is just ranting against features they don't like and don't even use or need.
