For me, in a sense, "liberal feminism" (if that is what I am - I don't really identify with a sub group but still), is often about realism.
Prostitution as an example:
I do not see how Radfems will achieve thier ideal of eradicating prostitution. Yes you could make it illegal everywhere in all forms, but drugs are illegal, speeding is illegal - still happens.
You could increase the punishments involved, but then murder has pretty severe punishments (in some cases death) and it stiil happens.
Yes, you could make it socially unacceptable....like say, drink driving (which still happens).
Yes you could (and should) raise the expectations and power of women along with their value in society. Well I think all feminist agree with that - rad, lib or whatever, but will that totally eradicate prostitution? Hard to say.......maybe, hopefully......but won't to take a long time? Yes.
So given that there is so clear, sure fire way of eradicating prostitution, no matter how much you may want to, and given that even if that goal could be achieved it will take a long, long time, shouldn't we consider the current reality?
What about the women who work in the sex industry now? Is it right to eschew any attempt to safeguard their rights and well being within the current reality? I don't think it is. I think you can look to the longer goal (if you wish) but still work to improve the current situation within the system short term and work to change it long term.
It's a great ideal to want prostitution eradicated, but should the pursuit of that goal (which IMO is possibly no achievable and certainly not in my lifetime) be of greater value than the lives of people currently working in that industry? I do not think it should be, so I think that makes me a liberal feminist.
