In our minds, it's not unreasonable that Canada should decriminalize the selling of sex because those involved are overwhelmingly victims of circumstance. We don't criminalize rape victims; we don't criminalize victims of domestic abuse. Prostitution is inherently violent and should be placed in the same category.
For us, the key piece of this legislation is reducing demand for paid sex. If no one pays for sex, no one is trafficked for sex. While obviously there is always going to be someone who is willing to pay for sex, if we can deal with the 80:20, we can prevent the abuse of literally tens of thousands of people in our lifetime. Plato once said that “Excess of liberty...seems only to pass into excess of slavery”. Allowing people to purchase sex will lead to the enslavement of others. This is not the kind of liberty that our nation should seek.
