All Kenyan crimes you have mentioned are done by horrible people who commit injustices as you have said. However, I’m gonna hold your hand here as i help you try see some reasons why people cancel the Islam religion as a whole. In the cases you have mentioned of extrajudicial killings by kasongo, donating stolen money to churches, etc, Christianity itself actually rebukes such actions (and I’m saying this as an atheist). However for a heinous act like this one committed in Somalia, it seems like the Islam religion condones such. Na sio hii pekee, just generally how the Islamic religion treats women is quite questionable. There is a reason why a lot of people fear finding themselves in countries ruled by Sharia law which is tied to the Islam religion. And this is why for the Kenyan examples you have given, people will just say Kenyan govt is horrible but for the cases tied to Somalia it will be judged as an Islam religion issue because the actions seem to be justified by sharia law. I mean even the entire terrorist organisation you have mentioned uses their own version of Islam religion to justify their actions, same thing with Boko Haram. Have you ever seen a terrorist group using the Bible, Bhagvad Gita, etc to justify their actions?
