For forums health:
Each make a thread (if you desire) to express your perspective, and anyone that wants to get involve can join you. Like any other recurring topic I think this is the best solution, and no need to have a recurring topic showing up around the forum. If this topic can be contain within these threads, then I do not think your replies should be deleted. There are plenty of threads, and replies that are not censored that I do not think the mods should babysit this topic.
Suggestion for your lives:
I would also suggest mute each other, since neither of you need the other's opinion on anything. You two have pretty good lives, opportunities, and friends that you dont need to even THINK about the other person.
Personally I think each of you is an interesting and nice person, and this issue will keep you from really enjoying what may lay ahead.
