Voicing concerns to someone who is non-responsive does nothing for innovation.  An example of non-responsive would be: "Hey, did you sweep the floor?"  And instead of answering the question they say, "Sweeping the floor would be a good idea."  The reply is an attempt to dissuade the need for a responsive answer like "Yes" or "No."

While I agree that voicing concerns is a good first step, if the replies are non-responsive, it causes innovation to slow.

Regarding the personal bashing, I agree it would be nice if people could move past it.  But it reveals information as well.  In some of these threads I have seen **a)** hard questions, followed immediately by **b)** a mix of responsive and non-responsive replies, then **c)** more hard and progressively more pointed questions, followed by **d)** tantrums and personal attacks.

It didn't have to go there.  Hard questions and even criticisms are productive.  Interpreting hard questions and criticisms as personal attacks reveals a fundamental problem.
