If you don’t like the way things are you can:

A) critique it
B) try to convince others to do it
C) talk / write about it
D) build the future yourself

I think of it as activation energy vs focus area 2x2 matrix

creating and destroying; flying cars, roc.camera, july.rocks

I always try to avoid negativity 

Guess we are all critics one way or the other

While i don't disagree with you in spirit - I find it interesting because this is like saying "I dislike negativity" 

In away, by criticizing those that criticize, you are becoming a critic lol
