Yet another strawman, because I have addressed this and shown that scribal corruption occurs when copied, not when the original being copied was written. Thus the dates of the manuscripts with the errors, whether deletions or additions is key. If you can't get this than you can't begin to do textual criticism.
Dr Wallace said the manuscripts without part or all of the additon were earlier and earlier still. Are you saying the dating given by Dr. Wallace is wrong?
The date of the manuscript is important when we are talking about an action of the scribes copying the manuscript, either adding the clause, the Dr. Wallace view, shared by CT advocates, and the deletion view, held by Byzantine advocates.
1) The earliest, according to Dr. Wallace had no addition of the interpolation from Romans 8:4. OTOH, you claim non-existent copies earlier that these, had the addition.
2) The next later batch had part of the addition according to Dr. Wallace. You claim these were flawed (from memory) efforts to restore the deletions supposedly in the earliest but non-existent copies.
3) The latest copies have the full interpolation according to Dr. Wallace. You claim these are actually copies, not from memory as the earlier ones were, of the non-existent copies containing the full addition.
4) Does not hang together at all for me.
