Delshad, I am glad you can see this topic the way I do. Please don't leave so soon. You might find something worth learning here. Even from creationists. For myself, I am active in this topic because most Muslims are ignorant about evolution, and Harun Yahya's trying to make creationists out of them. I want to stop him, that is why I use the discussions here to get the important points and learn the weaknesses of what I am trying to do.
Concerning the image of Islam here, I've done worse than you (look back at my suicidal exchange with Wordswordman) but these guys don't give a damn about it, we just go on with the fights. It's okay. There are other Muslims who are (were?) active in this site (Fedmahn, Syamsu) and they have their own views. You don't have to be afraid of giving Islam a bad name here.
If you still have some interest in the debates, don't hesitate to join sometime.
