Main problem for me is that humilition isn't related to sex scene but is sort of there in general. It's like if you go to work and simply humiliate someone because they are dressed badly or done something stupid. For me there is humiliation and bullying and Fashion Bussiness is more about the later. This is not about her being a willing slut or not, it's simply that she's a woman that whole world turned against her for her being bitchy at the beginning.
Example: If Monica was collared and leashed and walked outside naked, if she was choked on a dick a cummed on and than ridiculed, it's fine with me. If she's called 5 buck cocksucker repeatedly by some ugly moron just for the sake of it, then that isn't fine with me. It just pisses me off.
For me it's similar to BDSM. I can enjoy BDSM, even quite extreme stuff, but it has to be sexual in nature, not general. Tying, spanking, humiliating, that's ok. But if someone bosses you around, makes you do their chores, take blame for their mistakes, etc., than it isn't fine at all.
