Cara at The Curvature sums it up rather nicely:
So basically, men in NSW can no longer legally “believe” there has been consent with absolutely no basis for doing so. Unless they want to risk rape charges, they now actually have to make sure that the women they’re fucking want to fuck them back. They’ll have to do horrible things like communicate with their sexual partners and stop to find out what’s wrong when a woman is not actively engaging with and responding to their advances. They’ll be forced to ruin the romance by saying totally unsexy things like “do you want me?” and “do you like that?” instead of just shoving it in and grunting and thrusting away like there’s not another person there.
In short, a legislative body has finally decided that men deserve to be held to the standards of basic ethics and humanity. And a large section of men are mightily upset about that.
And now, of course, we have to wait and see how the law will actually be applied in court and whether it will result in more rapists being found guilty. We can only hope.
