Vanilla people only! Does knowing that S&M is an accepted part of human uality despite its sick and...?

It doesn't bother me at all. I personally think that what goes on behind a bedroom door between two consenting individuals is fine by me, and not really any of my business. It does not mean that these people are sick or twisted--most are completely normal, and just get turned on by different things. There is a big difference between someone who likes being submissive or dominant in the bedroom and someone who has the potential to be a criminal. In my personal opinion, you'd serve yourself well to be a bit more open minded, especially with a subject that has no pressing relevance to your life.
