Queering BDSM subcultures

I'm currently working on a big academic project on queer and SM spaces (and eventually some of it will be a conference paper -- eek!). I'm aware that plenty of communities around the world will tend to place BDSM under the big queer umbrella, if you like. But the community in the UK is not so keen to do this.

Pat Califia wrote in Public Sex:

By "radical sex", I do not simply mean sex which differs from the "norm" or heterosexual, vanilla, male-dominant intercourse. People whose erotic practices are deviant do tend to acquire an outsider's critical perspective on marriage, the family, heterosexuality, gender roles, and vanilla sex. Being a sex radical means being defiant as well as deviant.

In the UK, the majority of the community does not tend to operate from a critical perspective on most of those things. Plenty believe there are inherent, naturalised differences between the sexes that are merely acted out through gender role (and hence, often through BDSM), for instance, and many are in favour of performing to the world a normative presentation of marriage, family and gender role. With the recent advent of Max Moseley's "outing" and trial, the community has been called upon to make various statements to the press about our relationship choices, practices, etc. Of course, journalists will lift, re-word and use whichever segments of interviews they fancy (and a friend of mine found herself wildly misrepresented in a national newspaper as a consequence), but there has been this attempt to "out" BDSM in the UK as a tad fluffy, white, middle-class and Middle England -- and it's not just an impression that's circulated by the media: it's how the community want to be represented, in the main.

Obviously, I'm in favour of partially dismantling all of those things -- or at least the not-othering of choices that don't fit into those boxes. So, while BDSM in the UK is certainly deviant, we're missing that defiance -- or at least, we're missing defiance of social norms of the kind Califia's describing.

Given that this blog has a pretty international readership, I'm curious to ask: is queer viewed in a similar way within BDSM communities in other countries?
Do fetish clubs/events in other countries operate on a more pansexual basis? Is there a wide variety of sexualities and genders on display?
Is there a certain degree of social defiance and resistance to normative gender roles, relationship formations, marriage and family in other communities?*

*this isn't lazy research, by the way! I'm just beginning to unpick all these tensions, so here seems like a good place to air some of my concerns!
