Fundamentalists, in Christianity, tend more often than not to hold a stenographic and change-averse view of revelation.
Technically, a stenographic revelation would be one in which the divine words in a revelation are taken down in shorthand or recorded and transcribed, word for word, producing a complete, perfectly accurate written record of the divine revelation. Obviously, nobody knew shorthand or had a tape recorder during the time periods that the Torah was given to Moses, that the Christian scriptures were written, or the Angel Gabriel recited the words of the Qur'an to Mohammad. A "stenographic revelation" means, then, that the final written product, i.e. the scripture, is exact record of the divine revelation: in other words, the scriptures are claimed to be inerrant. Do Muslims claim that the Qur'an is a perfect record of the Angel Gabriel's words to Mohammad?
Yes, if the Qur'an is written in Arabic. Is the Arabic Qur'an a stenographic revelation? As far as I know, it is. I know of no Muslim who says otherwise. Do you?
I would agree IF the Bab and Baha'u'llah claimed to have accurately written words given them by God or a non-human agent speaking on behalf and by the command of God.
That is your opinion, which may be shared among those who agree with you. However, as disappointing as it must be to you and them, the fact is that there are Jews who would disagree with you regarding the Torah and there are Christians who would disagree with you regarding the Christian scriptures. Consequently, hell will freeze over before you can persuade your debate/conversation partners otherwise who believe that their scripture is a stenographic revelation. And the only thing you accomplish by telling such believers that their claim is a statement of faith but not a statement of fact is that you annoy the bejeezus out of them. So, if you enjoy annoying such believers, by all means, knock yourself out.
Personally, my own view of the Hebrew and the Christian scriptures is they are a result of participator revelations, i.e.
Likewise, I hold a similar view of the canonical Christian Scriptures.
