A ‘tax’ is a levy on voluntary activity. An involuntary directive to do something under penalty of law is a mandate, plain and simple. By your twisted logic a military draft is no draft, it is an 'invitation to serve.' The fact that it is mandatory can be glossed over, right? You just said so. You are an intellectual coward.
You have become the poster child for a much needed constitutional amendment - "Article III, Section 1 shall be amended to limit judicial appointments to two consecutive seven year terms. The second term must be re-nominated by the sitting President and re-confirmed by the sitting Senate."
This amendment is sorely needed since 'Justice' has obviously become a synonym for 'just another kind of politician.'
