Honestly I think this is the perfect place to vent and just say whats on your mind. I think the other threads on the forum are better for being rational like you mentioned.
I think we need to take out our frustrations every once in a while. Anger is a part of us and it shouldn't be seen as something negative just simply as a part of us. There are many silly people in the fight bin but at least some of us know what it should be used for.
