Dear committee member,
The question would be what gives you the right to speak in this tone to anyone.
If the dean, an AAUP member, confuses tenure track/tenured with FTE NTT, which I highly doubt he does, it would be our job to point out the error.
To keep these things clear is precisely the charge of this committee.
Professor and chair (as far as you are concerned)
