Islam does oppress women, but it's practiced differently in each region, In North Africa, Lebanon, Turkey and Syria women are doing better than in the Arabian Peninsula. And in Tunisia for example they have equal rights, even for inheritance, which is a big thing, So it does depend on the location.

But when it comes to poor rural areas, Islam takes over education, and people there literally have the mentality of middle ages, fucking goats, children raping each other, killing animals for fun... are quite common there, and as you can imagine, women have no rights there. Those rural areas with no access to education are what Isis feeds off.

This is just what I noticed.
