Here is Charlie Rose's superb interview with Andrew Sullivan, originally aired in September of 1995 while Sullivan was promoting his book "Virtually Normal." Sullivan lays out a superb, solid, passionate case for gay marriage...almost a decade before Massachusetts legalized such unions. This interview is Sullivan at his best (man, did I have a crush on him back then), but...
His argument that essentially gives a thumbs-up to discrimination in housing and the work place (his conservative soul can't stand hate crime laws) is a bit disconcerting. Coming from a guy who's led a pretty charmed life (B.A. at Oxford, Ph.D. at Harvard, editor of The New Republic by the age of 25, etc.), you have to wonder if he has ever been denied a job or an apartment simply for being gay.
That aside, take a look at the interview. The conversation is well worth the time.
