I've seen some posts that look like the posters think some people are advocating doing nothing at all in response to the attacks.

I could be wrong about this, but I don't get the impression that anyone is advocating doing nothing. What it looks like to me is that some people are advocating keeping a level head and not acting hastily, or out of anger, being careful to avoid hateful language and actions, and maybe most importantly, recognizing our own contribution to the current state of affairs in the world, and taking steps to correct our own behavior. I think it's all a matter of balance.

I think some people are asking others to be mindful of the difference between 'justice', and 'revenge', and to remember that our own behavior over the years has not been above reproach. So we need to ask ourselves if we are we willing to live up to the same standards of justice to which we would hold others?

I imagine my words might piss some people off, but I hope people will remember that since this is a place where we are all entitled to our own opinions, and since I have not flamed anyone, or behaved rudely in any way, people will respond with some kindness if they have any disagreements with what I have said.
