Your ignorance is all too apparent now. 

 *The term "British & Irish" Isles is provided for in English and in Irish Law, nowhere is the term "British Isles" provided for in law.

 *WP also follows the principle of not using terms which are not offensive, especially when the legal and factial term is largely similar and requires little extra effort to print".

 *I agree it is a question of terminology and the terminology you use(without wishing to repeat myself) is wholly inappropriate and offensive not only to me but the citizens of the sovereign State of the Republic of Ireland, I know this because I speak with them, work with them and mix with them socially, just because they do not use WP does not deny the reality that many of my fellow citizens are offended by the term, not only is the terminology you use in this case inappropriate and offensive, it is legally and factually incorrect in both of the jurisdictions concerned to which you refer.

 * I am sorry that the links are broken and rendered unworkable. The other points you make about the reference being less concise and widely-used etc. are not only very much debatable but do not justify its' usage.

 * I will put my point of view across in any forum I see fit, whether that be a forum of 3 people or 3 million people is my decision and I shall not be lectured to on how to exercise my freedom of expression and speech. Sometimes "vandalism" is the only recourse against ignorance, stubborness and egomania.

 * You are making another subjective assertion, the employment of sockpuppets is a tactic widely used by ones of a higher ego and insecurity to develop and give the perception of a consensus when none, or at the least am ambiguously minor one exists and for you to have the nerve to pontificate to me about one's suitability for WP is analagous to George Galloway lecturing to Kofi Annan on political sophistication and being "statesmanlike".
