Understood.  Thought that might be the case, but even so if a thread hijack can be nipped in the bud with stern warnings to repeat trangressors, then maybe it would help.  You wouldn't be censoring then, but you might prevent some of the shenanigans and make transgressors think twice about what they post to what thread.  Maybe a special "HiFi Fundamentalists Shoot Out Forum" to keep this stuff out of the main forum.  Those who want to can take their Jihad there and not bother the rest of us.
