I agree with the sentiment. You can make stylesheets for LaTeX, without changing the macros you call in your content, but it’s a somewhat arcane process. Go on the TeX Stack Exchange site and someone will explain how to do it if you want. I don’t need that. ConTeXt is better at this.

I’ve been doing my résumé in ConTeXt. Seems like it’s more expected in ConTeXt that you mess with the styling.

It’s reasonably common & expected in ConTeXt to define your own macros for custom sections or whatever you need. ConTeXt has macros to define macros…
