Well I don't know who Andrew Anglin is, didn't know what Daily Stormer was until I saw people talking about it on here, and wouldn't know who David Duke was if he wasn't being given tons of media attention.
If someone is linking an article to a mainstream news source does it matter if the person linking it is David Duke, LeBron James, Hillary Clinton or Tom Brady? The article is the exact same regardless. I don't go and investigate the person linking it because the New York Post and Good Morning America arent fringe news sources.
