"Homophobia, though, is woven just as intricately through the ideological fibers of this movement as its thinly-veiled racism-maybe more, said Ed Sebesta, who is gay and a longtime researcher of the neo-Confederate movement."
I also just checked around the web a little for more about his politics. In addition to the Pacifica stuff, it seems that he's a regular interview topic in those weekly throw away leftist "alternative" newspapers around the nation. He seems to have a particularly strong presence in one such paper. It is called the "Touchstone" and is apparently some sort of leftist publication serving College Station, TX and Texas A&M (their main page is covered in stories and links about anti-death penalty activism and "no war in iraq" peacenik stuff). Sebesta has given interviews and "expert" consultation on political correctness controversies they've covered.
I searched some of their archives and it confirms what is hinted by his website - he's a leftist conspiracy nut who thinks that the confederacy is the root of all things opposed to his radical homosexual agenda. Here's an entry he apparently made in their website guestbook at http://www.rtis.com/touchstone/comments/
"358 ed sebesta (Dec 15 2002 64.53.32.31) Trent Lott hates fags, always remember GAY PRIDE USA 2003 March on Washington. AIDS is just a bump in the road, hang in there my brothers!"
