As a feminist I'm not against porn or prostitution but I do see the potential harm in both, and while I am fine with the argument that both should be legal, I think it's important to be pragmatic and come up with logistically sound ways of protecting those who are sex workers or involved in pornography.
First things first, prostitutes are only being hurt by the current system. Because it's illegal, prostitutes are in a vicious cycle of being put in jail only to be released and have nothing else to turn back to but prostitution. Sexually transmitted diseases are a problem, and historically our government has shown they have little desire to speak out when groups such as LGBT people or sex workers are affected. Same goes for porn - there should be fair regulation to ensure actors and actresses are not taken advantage of, that STDs are not swept under the rug, and that shit like sex trafficking and the abuse of children and teenagers is eradicated.
I think there are parallels to drug decriminalization, sure, but in this case we are talking human beings, not substances. For that reason whereas I am fine with an overall laissez faire approach to drugs (and keeping non-violent users out of jail and giving them access to treatment), I do believe we have to be much more careful with people, especially in a field that is quite conductive to abuse, trafficking, and dishonesty.
