Disclaimer: I have no problem with erotica, that is not the part I find disgusting.

This book is disgusting and glamorizes unhealthy, abusive relationships and gives people the wrong idea about BDSM. In BDSM trust and safety are the most important things, and the fact that when she revokes permission and asks Mr. Grey to stop, he not only continues but also threatens her, makes this extremely problematic. That is rape, and this book romanticized it and makes it seems like it is okay because he is a rich white man.

Open your eyes ladies, this book is atrocious, even more so that is started as fanfic for another problematic series (Twilight - also beyond terrible)
