I think that’s rather dismissive when said content is simple text in the browser. Easy solution: don’t use fixed navigation - it is a very bad UX pattern for content/informational websites. That’s why scrolling exists. I assure you that users don’t require access to your menu 24/7 when reading through your website.
I wrote about this "sticky" header problem back in 2019. Seems very relevant to this current discussion.
Content is not simple text in this case. My site is designed for visual arts and experimental literature, including poetry.
Many other art-based, photography focused and creative writing projects work fine in my browser. You seem to just be avoiding the removal of bad UX patterns (fixed elements) for personal reasons - which is fine.
But you shouldn’t hint towards the fact that it’s “how things are” and they “can’t be fixed”. You’re hurting user experience for personal preference - not limitations.
