Comic Sans is a good typeface, actually

Eric with a shakedown of comic sans jokes:

Even though I put a lot of effort into selecting typefaces, I’m not precious about it. If someone changes the typeface, its font size, line height, letter spacing, and color to meet their needs, I’m delighted! It means that they’re interested enough in the content to expend effort to make it legible.

Why do you care so much about setting and overriding (see: dictating) someone else’s preferences?

The thing is, you can’t know what works for someone’s access needs, but you can provide mechanisms for them to help themselves, and that’s totally fine.
