Sure, but I want everybody to do it. I've seen too many times where a person presented an idea to a group, the idea was publicly shunned by the group, then later a few members of the group discussed the idea in private amongst each other as good.

When I was the one who presented something poorly, I've even had people who publicly shunned it privately tell me they support the idea but the group rejects is so they reject it publicly too. This is dumb.
