Even if it were true that BSD is ambiguous, your license is worse than
ambiguous because it explicitly denies the needed rights. As far as
Clear BSD (http://labs.metacarta.com/license-explanation.html), it's
obvious that their license is not motivated by a desire for clarity, but
rather a desire to avoid a commonly-understood interpretation of the
actual BSD license.
If it were true that "it is widely understood that the BSD probably does
not grant patent rights anyway", there would be no point to Clear BSD!
Their argument is self-defeating.

Your stated position is not particularly relevant. What is relevant is
the text of the license, which by your own admission does not follow
your declared principles.
