Qaulen was obviously gay

The blonde woman he casually shoots in the back three times like she was nothing..?

Also, this dialogue: 'You just don't get it, do you Travers? We're in bed now, joined at the hip, partners in crime. You've crossed over Travers, and there's no crossing back!'

Qualen was gay as you like - look at the camp way he removes his gloves or scarf, his constant mincing, camp speaking manner and the sense that he was grooming Hal to be part of his gang of gay mountain villains.

don't mind him, some insane people are just obsessed about worrying about the great gay menace everywhere...

It’s was a very diverse group of villains to be fair. Qualen was very progressive.

Qualen - homosexual
Kristel - woman
Delmar - working class Cockney footballer
Kynette - urban black guy prone to knife crime
Travers - brought his Southern charm

The film has quite a conservative message actually. The lives of our heroes living their wholesome rural existence are torn apart when a team of urbane, diverse city-folk crash land on their mountain and start killing everyone.
