You clearly know absolutely nothing about religion, you are straight up embarrassing yourself. I studied religion/M.E history for two years of my life, you won't see me giving medical advice or commenting on Chinese history.

Not all religions are the same, in the case of Judaism, it is an evolving religion where if enough rabbis agree on something, they can rule certain things in/out.

I copy-pasted this from another comment I made:

...For example, Judaism is an evolving religion, where if enough rabbis "vote" on something they can change parts of the religion. Which is why, they outlawed polygamy and they outlawed execution in 70 A.D.

In Christianity, Catholicism at least, there is a very solid tradition of questioning. Protestantism is less so, and many denominations of the latter are literalists.

Islam is the only religion where Muhammad is considered the perfect man, and the "seal of the prophets", and the Quran is considered to be completely authentic and never altered.

The whole notion of altering the Quran in any way is forbidden in Islam, as Muhammad executed anyone who questioned his opinions or anyone who "mocked" him in any way.

It would be completely taboo, whereas there are 40 denominations of Christianity for a reason.

The bible was put together by a committee who cherry-picked what they thought would please the people.

Muhammad on the other hand, well the Quran was a make it up as you go thing, where everything Muhammad wanted (sex slaves, executing people, conquest of infidels) was "revealed" to him and ended uo in the Quran. You therefore cannot change the Quran. You're not even allowed to read it in another language but Arabic if you're a Muslim or else that is blasphemy. Point I'm trying to make is that there are many different denominations of Christianity, some who reject the teachings of certain gospels, so on and so forth. Islam in different. It's submit or die.
