The consistancy and continuity of the novels are not canon but suggesting that TOS was inconsistant in this case was not accurate, er, flat out wrong, which is what I was commenting on in this case.
Changing the intent of TOS is dangerous even when it's in conflict with itself. The writers job should be to make TOS jibe with their own work, not the other way around. Their job is to defend and do justice to Canon, not reinterpret it or change it and declare it in error. The game master is never wrong.
