The idea that you "own your thread" is a mindset that contributes to the forum not working well. It's a cyclical thing that your thread starts off by expressing your own opinion front-and-centre in the title and introduction, and it steers the course of debate - the thread exists to discuss your opinion on the subject, not the subject as a whole. The main page of the forum ends up looking more like the discussion that should be taking place within a single thread, but it's disjointed and won't stay together over time so it can't easily be reviewed.
An all-opinions focus thread isn't going to form in this situation, at least without the mods working on merging and deleting threads. And which of these "individual post-threads" deserves to get upheld over the others?
Imagine if, instead of all these individual thoughts, the first person wanting to discuss the issue makes a thread with a neutral(ish) title: "October 2020 Housing War Feedback". Instead of each other person starting their own thread for their opinion, they make it as a post within that thread. They do own their individual post, but the thread itself has been made "for everyone" - it's not an opinion but a container for everyone's opinions.
It all starts from a different mindset approach to the forum - a shared space for everyone where the thread will be an ongoing public discussion on an issue, so opening posts are constructed accordingly.
