The apostrophe character you're using, whereever it was copied from, is illegible to HTML without clarifying its ASCII code. I'd recommend either using this character >> ' << or referencing this site: https://www.ascii-code.com/ and using what's listed under "HTML Number" - you can also manually search for characters not on the list as the HTML ASCII list has been expanded multiple times

That's what's causing the ’ and – instead of the angled variants of ' and " (presumably you're using ‘/’ and “/&rdquo from table slots 221-224)

forgot to add the semicolon on that last one but that at least demonstrates how they're used

div id="ul" is causing incredibly miniscule font in https://communist-revolution.neocities.org/ImportantCommieOrgsIntl whereas the initial ul (under CPC) without the div is legible, if a bit small; I'd recommend just using ul at standard text size rather than the div or 80% font size
