2016 Postmortem
In reply to the discussion: Black Millennials: "Hillary...invested in violence against Black bodies." [View all]kath
(10,565 posts)picked it up and posted it on their site on 3/11. (At first, another DUer who called it to attention on a DU thread (one of the first to do so here, several did so before I ever did) thought like you, that Bravenak wrote the comment on 3/11 - but see below)
The anti-Semitic statement (from the vile David Horowitz-owned FrontPage Mag) was posted in a comment to one of Bravenak's diaries on DailyKos on 3/7.
Someone on Kos snagged a screenshot of the anti-semitic statement at that point, 3/7, and the screenshot from FrontPage indicated that it had been posted "one month ago".
So Bravenak posted it on FrontPage sometime between when the article she was commenting on appeared on FrontPage (Jan. 20th or so, IIRC) and Feb.7. Hers was the 6th comment posted on the article, and she deleted it after she was outed at Kos on March 7.
