Sometimes text content can be interpreted as hostile when it was not meant that way.

So it is important to be charitable when reading ideas from people

Assume that your content was read

If you see a comment and you feel like the person has not read the document, do not tell them that they have not read it. This will probably be interpreted as an insult to somebody's intelligence or reading abilities.

Maybe they have read it, but there is a misunderstanding about the content. Maybe the document is confusing, but most likely this is a result of poor definitions.

Instead of saying that they have not read, use embeds and links to emphasize the content that you think they haven't read. This will highlight the underlying communication issue.

Assume that they did not forget

It is rude to tell somebody that they forgot something. Maybe they didn't! Instead it is best to just remind them, and ask if their opinion has changed.

We often learn things and change our minds over a long period of time. Especially if referring to big decisions from many years ago, its a good idea to revisit the discussion to make sure people are still on the same page.
