Once again you are having the same problem.
Christianity/Judiasm is bad because a group is doing something bad... (even though others do good)
Islam is good because this group is doing something good... (even though others do bad)
That's just sad. A non-muslim could just as easily point at the leaders of some Islam countries and the suicide bombers and say "See, Islam is bad". That doesn't make them any more right than you. In fact, you would both be using very poor logic.
