We might be worried about how the moral uncertainty argument applies in other cases. For example, homosexual acts
Actually, Iād like to amend my response here. I think there is a clear division between aborting fetuses and homosexuality here. There are strong non-religious arguments for its being wrong to abort a baby, but not very many at all for homosexuality being wrong. It seems that most of the disagreement about homosexuality comes from disagreement about whether Islam is true, which is a factual disagreement, not a moral disagreement. As such, moral uncertainty is much more important for the (im)morality of aborting fetuses than for homosexuality.
