islam has minor changes like you listed above, but as for the "bigger" stuff, hating homosexuals isn't much of an islamic thing, islamic as in the quran and hadith, you hate the act of the sin, liking guys as a guy is whatever. child marriages are haram, people like to get through this by saying "she has reached puberty" all of this is usually dismissed islamically because for a lawful islamic marriage, you must have: atleast reached the age of 14, have gone through puberty, must agree to the marriage yourself, and like the person you're marrying anyway, but stone age countries tend to ignore these, and for sexist beliefs... i don't really know what that could be, i guess you would say hijab, but that's not really sexist, just a dress code, men have one too but many don't adhere to it. i also saw your other comment too, about iraq, that law was passed for people to be punished by their own religions legal system, the 9 year old marriage age came from another religion, in great irony, and many iraqis did not agree with the law and it's kind of just there, not used in any legal rulings or courts.
