I'm familiar with Islam. Back in the 90s, I lived in an area with a lot of Arabs. I befriended them & would go to the masjid with them. Also, I attended halaqas. I learned a lot about the religion. It is more like a political ideology than other religions.
In Christianity, there is the idea of separation of church & state. But in Islam, there is no such idea. The goal is to make everyone Muslim or subservient to Muslim authority.
