The proper place to include that sort of interpretation is by adding it in a comment in the thread. Then your interpretation is on a level playing field with everyone else's (https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so...). Also, a comment gives you room to actually substantiate your interpretation.
On the other hand, a thread like this probably wouldn't have gotten attention without the sensational title in the first place, so this kind of submission is a borderline case and at worst a venial sin. (We still change the title once it does make the frontpage though.)
