Anyway, if discussions about violence spawned in random threads and destroyed them, we'd have an issue there too. Violence is worse than sex in an absolute way, obviously, but when it comes to a lack of self-control in discussions, sex is the clear winner. This isn't the first time Yanlin or Sofia have attempted to derail a thread with behavior like this. And additionally I'll point out that the thread wasn't locked, which means that Threetoe didn't think the thread was derailed. He just removed some rule-violating posts that were having a few ripples. Anyway, the thread's derailed now since it seems some people, including the OP, disagree with this decision.
The reason sex discussions are banned and discussions about violence aren't is because some of you can't handle them. A single off-topic mention is likely though not guaranteed to sink a thread. The rule was only created after numerous derails, not because we woke up one day and discovered morality. I don't think all discussions of a sexual nature would be banned in general if the community were up to handling them -- now, certainly, given the age of many of the forum members and general standards in my country, allowing sexual roleplaying or other such explicit discussions wouldn't work out. Whether or not that's something we should be doing is irrelevant though, because a segment of our community is not up to the point of having a conversation in a thread of that kind, and in fact couldn't keep it contained in such a thread in any case. The Various Nonsense forum proved that topicless joke threads, which is essentially what these would be, are not healthy for the forum.
In addition, this shit loses me money, if you want to get down to it, because many people don't want to be dragged back to junior high school, especially if they start a topic and somebody comes in and knowingly screws it up.
If you want to say I'm a typical American because I don't think several grade school posts about ass sex belong in a thread about symbolism of the word heart, and you disagree with the reasoning above, that's fine, but I don't think I'm going to change the rules, especially after seeing some of the responses here.
In particular, Armok, if you want to paint my brother as a stick-up-the-ass American prude without trying to have a discussion about what is obviously a defensible position independent of our own morality, you should recognize that you're the one having a knee-jerk reaction.
Yanlin, this isn't a tragic moment in the violence vs. sex debate. You're just a juvenile dipshit who can't control himself. You've been warned 11 times. Somehow, you've been cut more slack than anybody else, but I'm through with letting you waste my time. You're gone.
