Well having siblings
I can safely say that there's no way in hell I'd go there. I'm realy sorry I'm not able to find some of the studies I'm referring to at short notice on the internet while I'm actualy supposed to be doing work but there was a theory pretty prevelent in psychology that it's not so much being related to someone that creates the "yuck" reaction, more the familiarity of growing up with someone. I do remember reading a study into Kibbutz's (Basicaly large communes where childeren where often raised together more or less all the time) that found that the childeren raised together showed significantly less romantic interest in those that had shared their childhood. I guess I can sort of undersand that. I've a couple of close female friends I more or less went through school with, and the thought of any romantic attachment to them is.. well a bit weird realy.

So yeah, I'd argue that it's more the familiarity with the sibling, growing up with them and such that means we just do not see them in a romantic light. And yeah, you could probably replace "sibling" with childhood friend of the opposite (or same) sex. Now BMS had never realy seen his half sister untill adulthood (if I recall). Therefore I guess that familiarity with her just didn't exist making it much less of an issue for the two of them to cop off.

Yes. I raised this point.

Sorry
I did read the thread but I must have missed it. Can you remember the name of that damn Kibbutz study?

I meant that I'd said that if you've grown up with someone then it's bizarre to view them as a sex object.
It's gone a bit Wuthering Heights in here.

Yeah, I agree.
I get where Enzyme is coming from, in that if there's no harm and it's all consensual then where's the problem? But yes, I agree - veiwing someone you've grown up with as a sex object is a bit fucking weird. Which is why I don't realy see the problem in the case of BMS. The only real issue is the psychological damage they might both have from going against what is a pretty fucking strong tabboo in most societies.

As I said before
viewing anyone as (simply) a sex object might well be morally shoddy - it's not obvious what being a sibling adds.

And the psychological harm, if there is any, seems to come from the reaction; hence the reaction can't be explained or justified by appealing to that harm.
