I'm sorry that happened to your friend. Unless I've only seen the tip of the iceberg, I didn't think vice was that bad? Not always substantiative, and definitely a ways left of center, but I wouldn't stick it in the same vein as something like Infowars or breitbart.
But probably you don't have any actual metric or system for deciding "badness".
PC goodthink is that Breitbart is terrible in every way and the worst possible source of news. When I've compared its European edition to outlets like the Guardian, it's pretty similar in tone, style and content (obviously with political polarity reversed). If anything it's actually less extreme, for instance, it's very clear about the separation between illegal immigrants (i.e. a class defined by choice) from race (a class defined by immutable characteristic), whereas the Guardian does publish pieces talking about 'white people' or 'white men' quite frequently.
Also, Breitbart uses links to primary sources much more heavily than most news sources do. A lot of papers only link to other stories they published, to keep you in-site.
