Firstly, welcome to the forum.... and great name!
I have friends who are muslims (shia and sunni), evangelical, catholic, protestant, buddhist.... and all will claim that they can believe what they want. Hell, I have even had JW's claim it.
In some cases it is true. My muslim friend has come to accept evolution and has found a verse that he can construe to make it possible and he now ignores the ones that overtly contradict it. In my same year group is a muslim who denies evolution vehemently and believes that 6000 years ago humans were a few hundred feet tall (don't ask).
The reality is, the muslims would defend each other for their religious identity, to the death. They see what they share in common over what they conflict on. That being said, they are shia muslims and are in serious conflict with the sunni muslims, some of which I am also friendly with. It is truly bizzare. but it is the same with all the other belief systems. If you look at JW's they claim concrete solidarity and unity, but having visited congs all over the world, the views on many things change wildly. In fact you can travel from one congregation to another next door and see a huge difference in atmosphere and to what is acceptable and what is not. Much comes down to the personality of the elders in the local hall. Even doctrines change in JW's by region. In Australia, a discussion on fossils and dinosaurs will lead to comments about demons burying them to test our faith, something I found truly shocking. Enough people said it and agreed that it was not just one persons opinion in one cong.
An analogy that comes to mind for all these people is that of a mouse in a maze. A mouse in a maze will claim he has freedom, he can turn left or right. But in reality he is not free, he is restricted to the constructs of the maze, constructs and rstraints laid down by others. Real freedom allows left right, forwards, backwards, up, down, diagonal etc etc. Freedom is about perspective. A man imprisoned in a room for 20 years may feel free if allowed to walk in a yard For a few hours a week.
Coming back to conformity and unity. These mice may be able to turn left or right, but they share the same maze, so they are in that sense united, but not in freedom. The punishment for apostacy or blasphemy in islam is death, apostacy including the desicion to leave the maze.
As for the many sects of christianity including JW's, some are more sympathetic to personal freedoms than others, but in reality there is a shared framework or tolernces and beliefs, they all use the bible after all. Some will deny verses without a blink of an eye, declaring them simply wrong, some will die for that verse, just as one mouse turns left, another right. But a free man, in my opinion, doesn't even know the verse exists ;)
