I think you could ask what it really means to protest, rather than respond.
Essentially a film like that is people making an ethical argument, just like people trying to argue abortion should be legal to the very end of the pregnancy, or that men should be allowed to self-identify as women, or that they shouldn't.
Which is to say, it's people in a democracy engaging in the questions that are important to them, and trying to convince people of their viewpoint.
I am increasingly of the view that protesting that, rather than making a reasoned response, leads right to things like Mermaids trying to have the LGB alliance delegitimized and their charitable status removed. It's not making an argument about any of the real ethical issues around abortion, it's just saying, anyone who thinks this must be a misogynist and don't listen to them or you are too.
Well we can now see what happens when that form of political engagement is the norm.
