Ireland charges no tax on airline tickets, as my post said. Neither VAT, nor arrival or departure taxes. Perhaps you might like to apologise?
Not at all, if you read what I pasted above my comment from your post, it was that that I was replying to, hence the reason I included it within the post. I have no doubt that Ireland doesn't charge these taxes, but I do know that on most airline tickets, roughly 25% is tax and this is money that goes to the government, not to the airlines, or to the airports.
If my tone was taken as offensive to you, then I will gladly apologise to you, but the point of my post was not wrong, I could break it down for you on a typical ticket if that helps you
