Working out which discussion is being referenced at any time, out of a sizeable number, and tracking down the posts being referred to, would be a lengthy exercise. And a pretty pointless one.

When discussions about serious issue unravel into name calling and personal feuding it gets pretty irritating. And of course the outcome more often than not is the thread gets shut down - and if someone opens another thread to enable further discussion, it happens again.

Free speech requires self control.
