Here is an example of adding to the text
Revelation 4:8, in which the four beasts declare that the Lord God is “Holy.” In the Robinson-Pierpont Byzantine Text (2005) the beasts repeat the word “Holy” three times (as in the Textus Receptus), but in the Hodges-Farstad Majority Text (1985), as well as in the Majority Text based on Family 35 and compiled by Wilbur N. Pickering (2015), the beasts declare a nine-fold “Holy” (i.e., the word “Holy” is repeated nine times!).
So which version of the Byzantine text is correct? As Pickering said "Surely it is more likely that ‘nine’ would be changed to ‘three’ than vice versa." that is clearly an expressed opinion which he has now put into the text of scripture. And as he said "The manuscript evidence is badly divided here but I take it that two of the tree main lines of independent transmission, including the best one, have “holy” nine times, instead of three." So he favors what he considers the best line but he does not say what the oldest manuscripts say perhaps because they do not have "Holy" 9 times but rather 3.
We all should care what God's word is but that is the problem right there. Who gets to say what is God's word? What some call additions some call lost words.
Since I am not a biblical scholar and while you have studied what others have said you have not said if you are one then the best we can do is repeat what various scholars have said. You do not like what scholars have said that disagree with your view as is your right but I am not required to agree with your view.
I do find it odd that you say we should be able to discuss the bible but then seem upset that I in your words do nothing but oppose the discussions. What do you think we have been doing?
You are looking for me to agree with the opinions of the various scholars you like even when you tell me they like the manuscripts that have added words to the text as we see in Pickerings F35 text of Rev 4:8.
To quote you "You would rather have the man made errors. That is fine for you. But you should not stop others from learning the truth
