I think that it's safe to say that any tenuous affiliation Westboro may have had with Al Gore was pretty much over by the nineties. In '97, due to the Clinton/Gore administrations backing of gay rights, WBC demonstrated at an inaugural ball calling him a "famous fag pimp" and in '98, at the funeral service of his father Albert Gore Sr., they yelled "your dad's in hell".
Is that how it works?
Al Gore supported and was supported by a bunch of lunatics who grew even more unstable over the years.
