Two posts: (first post, second post) by Daniel Rodger, who lives in the UK.

Here are the six slogans:

1. ‘It’s a women’s right to choose.’ 
2. ‘Don’t like abortion? Don’t have one.’
3. ‘Keep your Rosaries off my ovaries.’
4. ‘Vote Pro-choice. Politicians make crappy doctors.’
5. ‘May the fetus you save be gay.’
6. ‘Stop the war on women.’

I had not heard #5 before. But here are the first two responses:

1. ‘It’s a women’s right to choose.’ 

Of course we all respect someone’s right to choose, it would make you seem like a moral monster to deny something western civilisation values so highly. However, clearly there are many circumstances where the right to choose has its limitations. No-one is trying to tell women they can’t choose what to eat or who to talk to but the idea that choice is absolute is nonsense. One must clarify what is being referred to when we talk about having a right to choose to do something. If I wanted to choose to shoot my dog or beat a child for fun you would likely be abhorred at the nature of my choice and tell me that I have no such right to do so.

Very few people think that we should be able to kill other human beings with impunity which means that the nature of this ‘choice’ begs the question and assumes something about the nature of the unborn. That they are different, less valuable, outside of our moral circle, disposable and whose geographical location justifies their killing in the name of Western autonomy. Clearly whether someone is male or female they do not have the ‘right’ to choose to do whatever they want. Dressed up in more philosophical language we would find ourselves responding to the bodily autonomy objection that has been suitably refuted elsewhere ad nauseam.

2. ‘Don’t like abortion? Don’t have one.’

Let’s try and use similar logic on some other moral quandaries, ‘Don’t like slavery? Don’t own one.’ Don’t like wife beating? Don’t beat yours.’ Don’t like child abuse? Don’t abuse yours. Don’t like strawberries? Don’t eat them. What this slogan does quite effectively is that it moves abortion from being something that may be an objective moral wrong that kills a developing and innocent human being to one of personal tastes. Very few people would accept that preferring strawberries over apricots is morally similar to preferring to keep slaves or not, yet this is the category the slogan is putting abortion in. Slavery is wrong because it treats intrinsically valuable human being’s as a commodities that can be traded and sold.

However the real crime of this slogan is that it promotes the idea that those who are Pro-life only think abortion is wrong because they don’t like it, which is false. Whether someone likes strawberries or apricots is a personal preference that no-one would disagree with, but equivocating between that and an act that kills another human being is absurd and assumes moral relativism. This leaves the proponent of such a slogan in the position of having no authority to tell us that neither slavery and wife beating are wrong if I happened to like them.  Lets get this straight, when someone who holds the Pro-life view says abortion is wrong they are not simply saying they don’t like abortion, they are saying it is objectively wrong regardless of how someone may feel about it.

His first post covers the first three objections, the second post covers the latter three objections.
