I thought my meaning was obvious. When decent people allow evil to occur by doing and saying nothing they are almost if not as guilty as the evil doers.
Well, I got that part to be sure.
I agree with it to a certain extent, but I do not believe things are that black and white in the real world. Since bad people do bad things everyday, the logical conclusion to reach from what you have said is that everyone in the world is equally bad. (Hey, that may not be so far off!

) I do not really believe that is true, though. There are situations when a good person has no practical ability to stop a bad thing from happening. In which case, it is unjust to say they are bad for allowing it to happen.
The problem I have understanding you is in applying what you are saying to this situation in a practical sense.
Are you saying that everyone in Iran is evil? Everyone in america? The world? What do you think the group you are talking about should do to stop this? I am not trying to put you on the spot, I just wanted to get more detail on the practical application of your view.
Just for a hypothetical, let's say there is a man in the area that is asked to participate in the stoning. On the surface, it would be evil of him to do so. But what if he is only doing so to protect his family from retribution? Is it still evil of him to help stone this woman? Is he not a victim too? He is powerless to oppose a system that will end the lives of his family and himself if he does not do as he is told. Self preservation is a natural tendency in all living things. Is he evil for not going agaisnt that tendency?
Let's look at another hypothetical: A man living in America. He goes to work, supports his family, breaks no laws. He has no strong moral opinions about capital punishment, but consistently votes for canidates that oppose it, because he feels it would be better not to have it for reasons of cost effectivness. Year after year, canidate after canidate, the executions continue. Is he evil because he only works within the system to effect a change? Is he evil because he does not donate his spare time to activism against capital punishment? Is he evil because he does not see a moral objection to it?
Which leads us to another question: How do we as a society, and then as a species, decide wht we will call evil?
