It doesn't accept patriarchy it demands it.
Women can't be trusted to be leaders. We're too busy pleasing our husbands and birthing out babies.
I remember asking about this when I went to a Islamic retreat in the early days of becoming Muslim, and the response was, well there's no such thing as slavery anymore, so there's no need to worry about it and Allah knows best. I thought it was avoiding the question but thought I would look into and find a reason to "accept" it. The whole "they wouldn't have anyone to take care of them otherwise, and its a fitna for them to be in the house of a man, he is seeing to their needs how merciful of a duty" was the alternative answer lol. There was a lot of alarm bells in the beginning, I'm not sure why I pushed them aside.
I heard this reasoning, too. Another one? "Most men had concubines at that time. The prophet had to let them have slave girls! How else would he have gotten them to convert to Islam? He couldn't have banned the practice!"
Also, if I hear "Allah knows best" as an excuse for something shitty in Islam again, my head might just explode.
Another variation, "God is to us what we are to ants. Ants cannot even begin to understand the way we think, why are you trying to understand God?"
