Muslim is not a 'race', it's a person who follows the religion of Islam and perhaps it should be said that many of these countries that have Muslims as the majority, have a different culture where it's within this culture, not the religion, that the misogyny thrives, mainly due to a lack of education and a misunderstanding of their religion. As often is the case, the religion is misinterpreted due to ignorance or taken out of context so that the men can abuse, have power and control over, women, many of whom are uneducated and therefore already in a vulnerable position - easy for the men to control. My point I'd like to try to make is that it is not the Muslim religion of Islam but the culture of the person's heritage that may be blamed. For those that revert to Islam, they don't have the cultural baggage so you don't generally hear of problems caused by reverts (unless they're total friggin idiots and go far beyond into extremism, which the religion of Islam forbids), and women that revert are generally white, educated and learn about the religion as is all Muslim womens' right.
My husband is an Arab Muslim, well educated, several degrees, most of his family members are doctors, engineers, teachers, etc., and loves his religion which never advocates male supremacy over women. I have never experienced from any of his male friends or family members, any utterance of disrepect towards women - on the absolute contrary! Perhaps I'm just very lucky.
In the religion, men have no right to disempower, neglect, abuse or violently punish women; men are the 'protectors' of women - but as I said, what happens is that certain cultures have these old patriarchal traditions and customs according to their geographic location, huge societal problems, a lack of education and alarming misinterpretation of their religion, all of which can be passed down through the male generations causing the harmful perception and treatment of women. Therefore any 'Muslim' man that harms a woman most likely has severe mental or emotional issues first and does not know his religion as he should, or may not even be a 'practising' Muslim. There are other countries, with other religions, that also have huge misogynistic problems, and not only directed towards women. India, for example, has had huge problems with acid attacks.

On a personal note, I suffered violence for years from my ex husband, who was white and an alcoholic. I was told by a family member 'that's just the way it is.. you have to accept it'. Like father like son.
In closing, what this man has done is absolutely disgusting and unforgiveable and I hope he receives a truly fitting punishment. Put him in a cell with women and let them hand out what punishment they think he should get - that might be some justification.
