Wow! Being called "conservative" is as low as it gets! I call "strawman" on your idea of how we see prostitutes. I think we're all aware of the complexity and variety of reasons to become a prostitute and feminists who oppose prostitution, despite what many like to think, neither look down on prostitutes or see them all as pathetic victims (although I think we can agree there are many who undoubtedly are)
Quite the contrary, I think we see the complexity of women's motives and empathise with them in a way you cannot because for you it is more academic. 150 years ago someone in my situation would undoubtedly have been a prostitute. That was a reality for so many women. Many of us have at some point in our pasts been offered money for sex, and if pushed for money, may well have considered it (or even done it) and so understand the thought processes that go through a woman's head when she is that situation. As a man, it is academic for you in a way it never can be for us, because the spectre of prostitution affects all women in some way or other and we are not yet so confident with our new found freedoms to be so blase about them.
Anti-prostitution feminists are not concerned with judging prostitutes but with removing the system of inequalities that lead to it. That should be very simple to understand. It is not a job like any other to the vast majority of women (which you seem to think it is). It has a very high rate of assault and murder and if you think that will be removed through legislation you are naive. You only have to look at the willingness of some men to torture and murder prostitutes in video games to see that sexual violence is part of the kicks for an element of punters and that, legal or not, that element will not go away unless we look at its root.
And the reason people have used the hypothetical scenario of your willingness to "bend over" for other strange men rather than have sex with other strange women (which you seem to think would be a breeze, but I suspect in reality would feel quite different - once again academic for you as it's never gonna happen!) is because hetero sex with strangers always comes with an underlying threat of violence for women that men in the same situation don't feel.
