45 years in the business here. Irritates me because often the offending "media" are some guy with a blog or a Twitter, Facebook or Instagram page that have no training and have never worked in Journalism.
This is the one that REALLY angers me. I have a degree in journalism and while I'm not directly in that field (I'm in marketing) for some reason I take those attacks sooo personally. We are trained to be unbiased. Are there some that show bias, yes, but to degrade media as this big bad and discredit them when they are trying, for the most part, to give people information is infuriating.
