If you look at the tenets described in the Koran, they really aren't any less equal than what's laid out in the Bible (new or old testament). Neither book does a particularly good job of that by today's standards. I would argue it's not so much a problem with Islam, as it is the actual implementation of it. So I think that your point in number 3 is actually a greater problem with societies in which Islam is prevalent. Certainly the actual book plays a major part in how things play out, as Christianity is no shining star when it comes to (gender) equality. But I think what's more important is how Islam's pillars are applied to society. Why are they applied so strictly? Why must they be applied to public policy, why not allow a secular society? I think those are some major issues, that I'd like answered.
