I hear a lot of people complaining about things amongst their peers. This is OK, if it’s just an observation, and you move on. However, if there is something festering, and you feel something more needs to be done, do it!
Generally speaking, the issue you’re discussing is the one you’re most passionate about. It doesn’t do anyone any good if you’re just flapping your gums and not getting anything done. So, just shut and do something or just shut your trap.
