With all due respect to LF, I think we can agree that (s)he is not (yet) a link in the transmission of the Mesorah.
That’s not the point. You rejected the whole idea of an unwritten mesorah, and you can’t do that. He happened to claim that he has a mesorah, and while you may or may not have a different one (and of course there can be machlokes between mesoros), you can’t dismiss it by virtue of its being oral, you can only say that it’s not your mesorah.
No one of forcing you to accept his mesorah, but you’re not merely saying that you don’t accept it, you are outright rejecting it, and that’s vastly different.
