Exactly this. People are not going to suddenly change their behavior if they don't even see that there are issues right in front of them. Keeping quiet, pretending as though nothing is wrong, hinders progress immensely.
I am not advocating pretending nothing is wrong. We've all (for reasonable approximations of 'all') acknowledged what is wrong. What I'm advocating is moving from the 'raise awareness' stage to the 'implementation and experimentation' stage.
