Quoting matt_weiner’s locking post to the recent games and literature thread:
“X isn’t a game”-style arguments were already implicitly included in the part that Dan quoted (“Don’t claim a type or style of game already accepted by the community doesn’t belong”).
No one in that thread was claiming that any type or style of work accepted as IF doesn’t belong. I cannot find a single instance of exclusion or promotion of exclusion anywhere in it. Quite to the contrary, it concerned categorization within IF.
Considering that the stated reason for the locking is in error, I believe unlocking it is in order. I don’t have much more to say on the topic, but a final comment summarizing my conclusions would be fitting.
