Lots of people have speculated that regarding Chuck. My friends and I spent time with Chuck every time we'd see Death - eating together, talking music, and just generally having a good time. He was always a great guy, which belied some of the things that people would say back then, and never once did he ever lose patience with autograph kids or other musicians. Anyway, we never questioned his sexuality because it never mattered. He wasn't the type of guy that chased the ubiquitous fishnet and mascara metal slut around the club, but he never veered the other way, either.
Chuck was a smart guy who articulated himself well when he spoke. He didn't like conflict, especially if it threatened physical harm (he HATED stage diving and once threatened to stop a show in Pittsburgh unless it stopped). I never once heard of him doing an interview or a show while chemically imbalanced. He took his job seriously. He didn't act like the 'typical metal moron' - no hotel rooms destroyed, no paternity suits, no drug busts, and no alcoholic rages. From what I've seen, Paul is the same way. I only met him once (and that was when he and Sean Reinert were in Death) but he conveyed the same spirit that Chuck did.
If either or both are/were gay, so be it. If every musician out there were as pleasant to be around and as musically gifted as those two, I wouldn't care if the whole damned industry was gay.
