You're confusing the absence of explicit consent for its explicit denial. Yes means yes, no means no, and starting things up without an explicit conversation is a long and convoluted debate... And what happened here was not that. This was firmly "no means no" territory. Once somebody has asked you to leave, that's a pretty goddamned firm "no".

Yes, there are long and troubling discussions about how so much of sexual advances are silent and how it's hard to discuss consent with those, but this story was way the hell outside of that grey area.

No means no.
