Okay, I'm going to forgive you ahead of time, based on simple, common ignorance of what S&M is all about that you even put it in the same realm as necrophilia or beastiality. Do you know that ANYONE who likes a little pat on the bottom during sex play, or to use scarves to be restrained with, is actually practicing some form of S&M? That's like.... 99% of the sexual population.
S&M is 100% consensual between adults who can consent. Anything else is torture, not S&M.
Absoulutely nothing to do with the dead, animals, children or non consenting adults.
(No longer commenting on above quote, new train of thought...)
While I do not (can not?) say the subject of beastiality could ever be beautiful, I see nothing wrong with someone exploring the information to further their understanding on the subject. Sweeping things under the rug, holding your ears and eyes and saying "la la la la I can't hear you" doesn't solve anything. Society does this all too often, trying to ignore things and hope they go away, rather than learning about them, and perhaps finding ways to combat the issues they feel need combating. (Such as respect for the dead, animal rights, children's safety, etc.)
