There is literally abundant fake news, primarily distributed through Facebook. Actual lies. [0] Whether Breitbart is abjectly white nationalist is more debatable, likely by design.
I was asking about fake news specifically on Breitbart. I know they exist online, even on "reputable" news sites like CNN (so probably Breitbart as well), but to claim Breitbart is infested with fake news is patently absurd.
No. Not two days ago, I listened to a self described white nationalist leader speak at length in his own words. He was not a made up smear, but a real person with real (awful) opinions, who now feels he has kindred spirits at the top of government. So, again, no, "white nationalism" is simply not "mainly a smear used by the MSM".
Breitbart itself describes itself very clearly as a champion for the neo-nazis that have re-branded themselves as "alt-right". Much of the news they provide is clearly misleading.
I wouldn't necessarily go so far as saying Breitbart produces fake news, however there are sites that produce fake news. Completely made up stuff targeting conservatives to make money. This is a very real problem and it needs to be solved.
