Negativity is like a virus. It spreads and spreads and spreads. It sits in the back of people's heads and they start to feel it too. I'm just providing an opposing viewpoint.
If I were to not do it, then even subconsciously, negativity will be there, and this forum would gradually become depressing.
Also, do note that I didn't go into the Smash thread with positivity regarding the CPP.
