It's not unreasonable because otherwise the single market wouldn't exist because member states wouldn't want to expose themselves to so much competition.

For Ireland having a low rate of tax is good because it it attracts multi-nationals looking for a tax heaven, and so still provides higher revenues than a higher rate would. But if everybody had the same low tax rates it wouldn't work because it wouldn't attract multi-nationals, it would just mean lower revenues for all member states concerned.

In Europe people might not like high taxes, but they do like high government revenue, and the public services, and national industry they provide.

His not, EU law state that member states must have a VAT (the EU's sales tax system) rate of at least 15%. It also has a minimum rate of corporation tax, which is what we are talking about in the context of Ireland.

In an economic union, like the European single market, it is not unreasonable to stop members from taking advantage and have overly-competitive tax rates.

Yes, but on Linux you have Konqueror using either KHTML or QTWebKit, you don't really need Safari on Linux.

The Commons can't use the Parliament Acts to force an extension of the term limit, but with the consent of the House of Lords they can, for instances of this look at the War Parliaments that existed for the First and Second World Wars.

Constitutional monarchy doesn't really mean that, Sweden and the Netherlands are constitutional monarchies, and they have a proper constitution.
The UK doesn't really have a constitution but a collection of old laws, statues and treaties, such as the English Bill Of Rights, the Magna Carta, and the Act of Settlement; and the concept of Parliamentary Supremacy.
Under Parliamentary Supremacy anything can be changed by a mere act of Parliament, it is only because of convention and tradition (and of course threat of electoral defeat) that stops Parliament from imposing things like the death penalty for speeding.

Yes, but you seem misunderstand the relationship that Switzerland has with the Vatican state. The Vatican's Swiss Guard is composed of a few hundred Swiss mercenaries. The only real relationship that the Swiss Confederation have with the Swiss Guard is that they hold Swiss citizenship, and enjoy an exception to the no-swiss-citizens-are-allowed-to-be-mercenaries rule.
A war with the Swiss Guard wouldn't be a war with Swiss Confederation.
