And, a fellow smoker (regardless of political affiliation) contracting a smoking related disease should, in my opinion, be fair game for discussion on a smoking related blog.
The other thread didn't disappear because of discussion about diseases. It never got there because right from the start, that thread was derailed by politics. It had no value to the site, so it went bye-bye.
As long as this one doesn't go that way it will remain open. As soon as political posts start.....closed.
And as an aside, I'd like to know if this subject (a subject pertaining to smoking in general) is taboo? And how and why do threads just DISAPPEAR?
Smoking related disease discussions are not taboo, but some types of other discussions are. If there is a thread started that is of a nature that is against the rules, it is gone.
If there is a thread that has no value to the site, it will probably be gone. This is a pipe and pipe tobacco forum, plain and simple.
Don't just assume you may know why a thread no longer exists. If a thread is gone, it is done for a reason. And not all reasons need to be explained.
It's pretty simple, follow the rules and threads will remain open and not "disappear".
