I've been trying to assess that myself with questions to
@muhammad_isa, which he either disregards or answers ambiguously by using words atypically (abuse, mistreat, violent).
Here's what we have to work with, and why I'd suggest that his posting means that Muslim men with that attitude are very common. He probably didn't come up with this idea on his own, meaning it is likely a common Muslim teaching. He feels pretty comfortable expressing it, which suggests to me that he has social support for his views - a community that agrees with him and reinforced his beliefs.
I practiced medicine in rural Missouri, where there were several Muslim physicians that I worked with, but they were pretty clannish, and we didn't socialize, so I had no idea what went on in their homes. Now I'm wondering. How many of these men were raping or otherwise manhandling their wives? How many were second-class citizens without rights in their own homes, and nobody knew, because they don't talk about it?
