Maybe NSFW: Would you go along with / accept a friend's role in an active BSDM relationship?

This question could be uncomfortable for some, but probably NOT on Fluther so I am posting it here. How do NORMAL people (presumably YOU) react if people you know agree to be in a relationship involving, I guess we can say, ABNORMAL psychology ?

NSFW meaning that this question is maybe Not Suitable For Work, and maybe you stumbled upon it accidentally. But this question does NOT necessarily infer YOUR interest or involvement in such activity. In fact, it involves your reaction to, or willingness to observe and stand by, such activity if it involved someone you know.

If you had a friend in a completely voluntary, consensual relationship, involving Bondage, Discipline, Dominance and submission, sadomasochism either as the dominant or submissive, would you go along with it, if your friend, or rather, if BOTH participants, wanted you to?

Remember, I’m not asking if YOU would be a partner in such a relationship—that would probably be too personal to comment on online on Fluther. But if you could bear KNOWING someone in such a relationship and being around them.

Let’s say your friend actually wanted to be the submissive, or for that matter, was the dominant one living with a submissive in a BSDM relationship. One of the partners was treated like a slave, animal, or with utter disgust/disdain and kept in some kind of loveless and deprivation-involved bondage or humiliation role.

In such relationships, a person gives their permission for certain acts as if consent has been waived. It is an agreement where comprehensive consent is given in advance, with the intent of it being irrevocable under most circumstances.

You don’t necessarily PARTICIPATE. But would you visit the home of the friend(s), do normal things with them in public, and accept the relationship? Or are such relationships just too bizarre?

I’m not necessarily talking about anything TOO flamboyant—maybe a person is a slave and kept in a cage or treated like an animal, or with disdain and disgust. and endures what would otherwise be considered physical, emotional, possibly sexual abuse, but it was consensual.

Say your friend is in such a relationship. Do you accept their roles and go along with it, or does it seem too strange or abusive? Or maybe you’d be too concerned about the friends involved?
