Even though this is a thread about current events, I think it is very relevant to discuss the sources of comments and the slant that is given to particulars of an event. I have read articles written by the journalist that you mention and I find them shallow, misleading and ill-intended. It is not that fact that they criticize Letizia but the way in which any particulars are taken and are twisted in an ill-intended way.
Everything, absolutely everything can be taken and twisted in such a way, is that journalism? Ethical journalism? As a journalist, you report the facts period. You do not color, use innuendo, etc. You let the reader arrive at his/her own conclusions. One personal opinions are just that, personal opinions. That does not make them facts, solid journalism, even if one has a journalism degree. Do we compare tabloids with serious newspapers? They are simply not on the same league. One thing is to write something on a website and a very different one, having one's column published in a regional/national newspaper. Even then, one digs deeper, what is the paper's political position, etc. A journalist might have a journalism degree, many people have, but that does not make the pieces they write something trustworthy. When I look at a piece of news, I think sources. Where was this reported? By whom? Whe one follows coverage and repeatedly finds untruths, innuendo and twisting of facts, one learns to take what one reads by that media person with a grain of salt. At least that is what I do. The fact that something supports one's personal opinion of a situation or a person does not make it a fact or the reality.
Royals and the institution itself answer to the people. Letizia married into that institution and the Spanish Royal House has a say in what she does and how she does it. The fact that there is nothing else to criticize but how thin her arms are, how ugly her shoes are, how boring her outfits are, I find encouraging. She is doing her job and she is doing it well. She is the Princess of Asturias -some people like her, some people do not. Some people like the King, some do not. Some people like the Queen, some do not. Some people like the institution and some do not. It is just the way it is. People are entitled to their opinions. However, in every field there are opportunists. The fact that people need to twist and turn little things because they need to find something to criticize, to fill out space with Letizia's name so that it generates traffic to their site, I find understandable. She sells. And since the Royal House has not made her available to become a media commodity, some people use pedestrian criticism to make a sell anyway. My two cents.
