Mafia Style "Voluntary"

Voluntary means voluntary, right? You know, you get to choose. But in the Brave New World Order where words are being redefined. A very relevant example for small farmers, homesteaders and pet livestock owners (e.g., horses) is the April 2006 USDA document which talks about the USDA’s proposed National Animal Identification System (NAIS) being voluntary (page 1, paragraph 3). This is a switch from the past strong usage of the word mandatory. The USDA, in this document and its press releases, seems to be trying hard to tone down the language and avoid the term mandatory if possible.
