The question isn't whether the argument is "technically valid in accordance to how logicians are taught deductive logic" but whether YOU consider it valid or not.

You answer the question or you do not, at your pleasure. However, it's apparent you did not given your initial comment as well as what you say here.

Also, I use "valid" as ordinarily used today in deductive logic and for the last 2,500 years. And indeed, given that mathematical logic doesn't use "valid" as ordinarily used in deductive logic for the mast 2,500 years, then, obviously, mathematical logic doesn't use "valid" as I do. There's nothing I can do about that except repeat myself.

No, here, that's a very different issue, specifically that of equivocation. Nothing to do with the issue at hand.
