Markos kind of stepped in it too, with this Goldberg story.

I don’t have to worry about dKos writers getting arrested for trying to incite terrorism. That’s a conservative thing http://t.co/yYtGW1FIzC

The story he links too explicitly states that Goldberg wrote for Kos as Tanya Cohen.
Did he even read the article?

Goldberg also had another alter ego, Tanya Cohen, whom he attacked using Michael Slay on the Daily Stormer. Cohen was evidently a parody of far-left social justice activists. Slay called her “a Jew bitch who specializes in writing about how the US needs to ban ‘hate speech’ and any other speech that goes against the Jewish cultural Marxist agenda.” An email in Tanya Cohen’s name was linked to Goldberg’s IP address, and articles in her name appeared on Thought Catalog, Daily Kos, and feminist website Feministing.
