1.One of them is the moral permissibility of various practices.

一是多种行德是否允许。

2.Do you think it's possible to decide whether abortion should be permitted or prohibited without taking a stand or making a judgment about the moral permissibility of abortion?

你认能否在对堕胎德容许性何立场，也作何评判情况下，来决定是应该允许还是禁止堕胎？

3.The other is the fit between certain practices, whatever their moral permissibility, with the honor or recognition that the state should accord in allowing marriage. So Steve has a pretty good counter argument.

二是论德上是否允许，特定行是否应该得到国家尊重以及认可，并且相应地允许婚姻。所以史蒂夫反驳很出色。
