Yes.
Anyone remember Buckley and Vidal at one another during the '68 convention? Buckley wasn't always grandiloquent...
...the men were arguing about Freedom of Speech in regards to American protestors displaying a Viet Cong flag when Vidal told Buckley to "shut up a minute" and went on to call him a "pro-crypto Nazi." The visibly livid Buckley replied: "Now listen, you queer. Stop calling me a crypto Nazi, or I'll sock you in the goddamn face and you'll stay plastered."
...but it got the point across. ;-) BTT.
