Although I do my homework on the basic rules of the game in Montreal, I don't really know much about C-36 and the public debates around sex work in Canada. One thing that gets a bit confused in this thread is the word "feminist," as if all feminists were trying to eliminate sex work in all forms--or worse. Obviously many women's groups have opposed the legalization of prostitution for centuries (think of the temperance societies in the old west), but in fact most of the advocacy being done today in favor of decriminalization and legalization is being done by groups that would strongly identify sex work as a feminist cause. A good case in point is the recent New York Times article on whether prostitution should be legal; as the subtitle said: "A growing movement of sex workers and activists is making the decriminalization of sex work a feminist issue." So, to the degree that we believe that sex work should be decriminalized, we are in the feminist avant-garde!
EB's point, though, is a good one. Most people who have an investment and care--the clients, obviously, but also many of the sex workers as well--can't get involved and need to remain anonymous. I favor the legalization of marijuana and at this point in history I'm not taking much of a professional risk in saying so; but I certainly would be cautious about going on record as favoring the decriminalization or legalization of escorting, even if I were to do so in terms of human rights or libertarian principles. Perhaps there is a way to put our money where our mouth is (a phrase that has many meanings in this context) and support advocacy groups with donations. I don't know.
I wonder, overall, if the recent trends in the US toward a more liberal attitude toward sexuality and sexual identity (the LGBQ movements, gay marriage, etc) combined with some of the other loosening of moral pieties around personal behavior--at least in the blue states--might have an effect on the "hobby."
