People are taking it too much to heart or seriously. It's just a story. It's fiction. There isn't hardcore BDSM in it, just light. People are getting all worked up about and just need to relax. The woman isn't a professional writer. You either liked it or you hated it, as with any story. This is just one take on a relationship, no where is it said that this is how it is with everyone. It isn't accurate but then again, it's FICTION. There are stories written about many lifestyles that portray them in a different light.
I'm not trying to be mean, but SO many topics have been created about this and it's just getting old. I read the books, I enjoyed the little suspense it had about finding out "secrets", the sex scenes were okay at first but got predictable. This was fanfiction, names were changed and it was published.
Most adults that would develop an interest in BDSM would probably do a google search or get a book on Amazon to find out more, not just take what 50 Shades said because there wasn't much. And most people keep that stuff private that participate in it, it's not like a scarlet letter and everyone is going to know. So, if some people take it seriously, who cares what they think if you know the truth and what is right?
