And we won't deal with the elephant in the room or listserve.
If by politically correct however we mean sanctimonious taboo ridden speech--rather than challenges to the abuse-- what could be more politically correct than opposition to stell cem research, abortion and gay marriage (which of course can't be a better idea than marriage in itself is). The sanctity of life and (patriarchal) family. Don't read French but perhaps Dominique Lecourt's Humain, Posthumain needs to be translated. This book seems to present an altogether different kind of challenge to political correctness. There are some important obstacles to free biological inquiry and experimenation. And perhaps we'll need a politically incorrect ethos to challenge that. To me this is a much more interesting question than the sins of the left.
