I certainly agree with you about neoliberalism, Beach - but neoliberalism is anathema to poststructuralism (by the way, I think a lot of postructuralism offers something towards solutions, or tries to; but postmodernism in the Lyotard/Baudrillard/Jameson form I see more as negative critique).
On architecture, though - when so much of the discussion is taking place around rights to spaces, do you really think architecture isn't relevant? So Jameson, say, points out that postmodern architecture is all about how spaces must be sexy, permeable, flowing, filled with screens and opportunities to buy stuff, rather than being, say, functional, or spiritual, or sacred to specific groups or communities. Doesn't that have some kind of connection to a rights-based discourse that says you have no right to exclude me from your spaces ?
An architect in my family once told me that the reason there are never enough women's loos in new buildings (as opposed to old buildings, where the reasons are different), is that some architects believe that equality legislation means that if they build in more women's loos then they are discriminating against men. I don't know how true that is, but it shows something of how relevant architecture is.
On another thread I read in FWR a student gave the example of how the women's loos at her university had been turned into unisex loos. But unisex loos are sexy and permeable, and the menz can use them too, so why should women need separate loos by virtue of their biology when unisex is so much more now?
