It is a common place to affirm that politics consists in choosing the least bad of two deficient alternatives and that democracy serves to oust those who do not do well. In the Declaration of Independence of the United States, in 1776, Thomas Jefferson wrote that “all men are created equal and are endowed by their Creator with certain unalienable rights, among which are life, liberty and the pursuit of happiness”. Citizens have the right to be free and to try to be happy.In Spain, for years we have found ourselves mired in a confrontation that has turned politics into a war of communication where anything goes to harm the opponent, who has already become an enemy. We have moved away from the principles proclaimed by Jefferson and practiced by Adams, and we have built a political environment based on what is negative and bad rather than on what is good and positive, and on the fact that telling lies is "legitimate" if it is effective. "That's politics," they say. It is not.It doesn't matter if a person hasn't broken the law or abused their power if I can accuse them of doing so, with false reasons or half-truths. Once the accusation has begun, social networks will do the rest and, from anonymity, will convince many that what is not true is true. The problem is that the enemy of truth is not lies, but half-truths, which, by containing part of the truthfulness, make it difficult to discern the degree of falsehood.
