It cannot have escaped you that it's becoming more and more common for people to blame "mainstream media", "legacy media", "liberal media" as an excuse to dismiss things that don't fit well with their world views. As if the degree to which a story aligns with those views is a measure of the source's reliablility. I'd say it's gone so far that anyone using those terms is flagging themselves as a closed minded individual. It's one thing to criticize the media, quite another one to write them off a priori and seek your news inside your comfort zone. I suppose a facile counter would be "that's exactly what liberal people do by only sticking to mainstream media". The problem there is that despite real or perceived bias in traditional journalism, there is still a measure of accountability in that system. Generally speaking there's very little of that in the echo chambers of the internet that some would put forward as the alternative.
