Re: Berman as bigot.
To be fair, the sense that I get from all of that is not so much that Berman is a bigot as that he's... I don't know if there's a word that's been developed for it, but, if there's a distinction between racism and ethnocentricity, I'd say that it's the same with Berman. "Heterocentricity?"
The queer studies people I know prefer "heteronormative": broadly speaking, the assumption of heterosexuality and consequent marginalization of any state of being or mode of life that differs from the common male/female dyad. This might actually be the better word considering the examples that
BillJ raised and
Andy's subsequent debunking of them: such relationships were not
entirely ignored, but the episode always ended in such a fashion as to deny the idea that such relationships could take place, raising the issue and then dismissing it.
That said, it's general my view that 'ethnocentrism' or 'heteronormative' are passive stances, taken not out of malice but ignorance and lack of sensitivity, whereas racism/cultural chauvisism and heterosexism or homophobia would be the active modes. And while you're right that I've never heard of Berman applauding funerals or any of that Westboro Baptist shit, there's a difference between not including gay characters simply because one never thinks of it, because of limited contact, and actually playing a blocking role against people who do want to include LGBT characters/themes into the show, a stance of active denial. This is more than a failure to take a stand--something which I've decried Trek for in the past, even when I thought it was just a reflection of general television conservatism--but an outright refusal to do so, and preventing people who did want to from doing so. I would call that a prejudiced stance.
