People in different cultures think very differently about abortion. Abortion is not seen as a moral problem for example in Sweden or Russia, but it is seen as a difficult moral problem in China and in the USA.
It is true (independently of our conceptualisation) that it is wrong to inflict pain on a sentient creature for no reason (she doesn't deserve it, I haven't promised to do it, it is not helpful to this creature or to anyone else if I do it, and so forth). But if this is a truth, existing independently of our conceptualisation, then at least one moral fact (this one) exists and moral realism is true. We have to accept this, I submit, unless we can find strong reasons to think otherwise.
The kind of values for which I was supposed to kill, such as democracy and national independence, were better served, I thought, through non-violent action.
