No matter how hard this is to accept we have to hold on to the fact that humans did these vile things to other humans. This is the reality that has to be faced. The people that did this will say they are fighting the terrorism visited on them by the US and can show many such images.
We need to all believe that we have an equal right to space on this planet and that no one group has more right than any other.
If we start to believe that the people that did this were guided by Satan then we are losing sight of the real reasons, however unappealing they are.
That said there can be no room on this Earth for any person or group who will try to bow the will of others to their own in such a vile and cowardly way. They will not succeed. They will not continue. They will not have their will in this way.
Not all that are Muslim are to be hated and not all that are Christian are unblemished (you only have to look towards to Britain and Ireland to know this). Please keep in mind that people have done this, however hard that is to accept. People now have to decide how to respond. It is a free choice and we all have to make ours without the added hysteria of pictures in flames, smoke or clouds - aren't things difficult and frightening enough as it is?
