It doesn't mean you can have the mentality that this topic your personal playground to do whatever the forget you want. If you want to do something not pony related like play army like a little kid military RP start your own topic.
I wasn't implying that it was a "do whatever the forget you want" sandbox, just that you can only discuss a subject like this for so long and that the topic is better off just being a brony discussion thread.
Even in this case the thread is bound to be mostly ponies anyway if it weren't for the arguments.
