I agree with the above, why trust Oxford? That would be like trusting Berkeley, maybe I'll say, I assume Oxford has a liberal bias. If the article cites Breitbart and Infowars, did they look at the Huffington Post, Crooks and Liars, PoliticsUSA and Media Matters, etc.
Conservatives are possibly more active on the internet, Breitbart and Infowars are fairly big websites I gather, at least Breitbart, Infowars has little credibility with me. It depends on how they made this study.
Pizzagate, things like that, undoubtedly are bad news.
