Though, to answer seriously (Note, I comment as someone who has absolutely zero interest in ever seeing the book or movie).

[quote=Gonzo]Not only does he stalk Anastasia, but takes her home, undresses and changes her (while she is DRUNK), then tells her he is going to keep tabs on her for "her benefit."[/quote]
[quote=Gonzo]What does Christian do after submitting Ana to her first (and very traumatizing, I might add) experience? Leave. Yep. That's right folks, he leaves, and on top of that, gets mad at Ana for not telling him she was hurt[/quote]
[quote=Gonzo]he undresses her while she is drunk. He tracks her phone. Sends a shit ton of emails and texts, that in some parts of the books, make her uncomfortable.[/quote]
[quote=Gonzo]In fact, it most likely will show guys it's okay to be a total ass hole, and an abusive fuck[/quote]

This basically just sounds like Twilight (Which scaringly enough, my Mom is also crazy over... My Mom has issues with taste in books and movies :/).
Like seriously, this is the same routine over and over again now.

Guy's an abusive prick, but he's dark and mysterious about it... and dangerous, so girls gush over it completely forgetting the fact that the dude is a fucking manipulative asshole! >.<
Based on your description, the only point I can give 50 shades over Twilight is that at least the Girl isn't also a manipulative/abusive bitch.

[quote=Gonzo]-A bunch of BDSM stuff-[/quote]

By the way you spoke in this I assume you take part in BDSM frequently?

I myself am a Virgin, so I have zero sex experience... let alone experience in kinks.
But I do know people into that shit, and from what I understand from them it really is a insanely caring and loving practice.
Just one that's constantly painted by media to be bad and dark because it involves bindings, and some level of (consensual) pain.

But honestly? That is hardly surprising.
We live in a society where sex is still a hugely taboo thing, where stuff like "No sex until marriage" are still very common concept's and practices. And where people like me who are "Save sex for someone you love" is also very common. A lot of people see Sex as primarily a bad thing save for certain circumstances, as a taboo thing. It makes sense then that more extreme versions then are seen with a shade of negativity (Pun not intended) and a lot of the fans/readers of such book are drawn into it cause of the mysterious/danger factor.

Essentially, if casual sex was more widely accepted and more people were willing to try non-traditional forms of it I don't think stuff like 50 Shades of Grey would have nearly as many misconceptions made, nor would such books have such a big following in the first place.
