Halakhah su Salmi 31:13

Because of these reasons things have come to such a pass that one says whatever enters his mouth to say, without first considering that it might enter the category of rechiluth and lashon hara. (In our many sins), we have become so habituated to this sin that in the eyes of many men it is not considered a sin at all — even if he would say something which is apparent to everyone as absolute lashon hara and rechiluth, as when he would speak of his friend and demean him to the very ends of degradation. And if one asked him: "Why did you speak lashon hara and rechiluth?" he would think in his heart that he [his chastiser] thought to make him a ["fanatic"] tzaddik or chasid, and he would not accept his words at all, regarding this [(lashon hara and rechiluth)], in our many sins, as completely insignificant.
