I'd say you are also lumping a lot of things together as 'being about sex' which, while including sex, are objectionable on other ground entirely. Adultery, for example, pretty well invariably involves lying and deceit with one part of the couple being exploited, and I'm not in favour of that. Prostitution can be between totally consenting adults, but has always included a background of pimping, violence and other exploitation of the woman, and in modern times sex-trafficking. 'Any other form of extra marital sex' can again be entirely consensual, but equally can fall into the kinds of objections to the first things I listed. Abortion a lot of people find objectionable for the reasons Kevin gave and it is reasonable for a church to express a view, whether you or I agree with it or not.

I won't go through your whole list, because like you there are some things in it which I think are right to object to and some I don't. But I do think that it is a good idea to ask whether each is objected to 'because it is about sex' or whether it is reasonable to object to it on wholly different grounds, such as one person exploiting another.
