Is there the possibility to set up a Facebook account so that the owner can still read people's content and use messenger, but without the ability to post comments?
My dad uses Facebook to keep in touch with his friends and relatives. He is getting older and is starting to sometimes post comments that are offensive or ludicrous.
Any suggestions?
No Umberto, it is not possible to disable the ability to comment on your father's Facebook account. There are some parental controls and default privacy settings for teenagers aged 13 - 18, but they are intended more to protect the minor from the community, not the other way around.

If Facebook is being accessed through a web browser, you could install a browser extension such as uBlock Origin and use that to transparently remove the "commenting elements" from all Facebook pages. See my solution on this forum for removing "Google Login" prompts. That solution could be adapted to remove Facebook commenting elements from the browser.
