If I put a note in my profile that I like full-width text (like HN) and think the font size (larger than HN) is reasonable, do you think that'll stop me getting these same comments every time I post something to HN?
Since you're posting your articles to HN, you obviously want people to read what you write. If you want more people to read your writing, then consider making it more accessible and easier on the eyes.
People exist with visual disabilities and giant walls of text in layouts such as yours might as well be a magic eye puzzle.
Yes, you like it and can do what you want, but you're throwing sand in the eyes of people you want to read your stuff.
HN itself has wider text and smaller fonts than my site. So it should be in line with what the HN readership (taken as a whole) likes. (Yes, I see more complaints than compliments, but that's always to be expected)
Visual disabilities are an argument for having a font size consistent with the rest of the web and a site where browser zoom works, not for making your text larger than the rest of the web.
