You read minds now?
Like andie said, Yoshie, I'm a little too old to get interested in anything simply because it's transgressive. I take an interest because, my own experiences of sexual marginalization, which didn't feel transgressive but quite painful and lonely, mean that I care about others who have similar experiences. It means I have an open heart and mind and am curious about someone else's life. And if they want to explain it, I listen.
None of the folks I know claim sexual practices lead to liberation or are subverting dominant power structures. There have been countless blog wars in Feminist Bloglandia since there is a vocal minority of feminists out there who are convinced BDSM is a pure instance of patriarchal evil -- the model of male control of women. (There is a long convoluted explanation as to why the existence of male subs is not a refutation of that claim) During these wars, most people who are practitioners want 1. people to leave them the hell alone and 2. want people to quit speaking from ignorance and making judgments on them -- including the judgment that they only enjoy it because they think its "transgressive".
