Except that the issue of consent that usually comes up isn't covered in this video at all, which is;
What happens if someone has been drinking, enthusiastically declares that they do indeed want tea, happily drinks the tea, and then wakes up the next day feeling unwell and says "Urgh... I didn't want that tea after all... I shouldn't have had the tea."
Not being flippant here, just pointing out that in the VAST majority of cases, people do already know that "no means no" and that you shouldn't sexually assault people in their sleep. The issues of consent that need to be addressed surround the issues of "what constitutes capacity to consent", "How drunk is too drunk", "Does ANY inebriation = too drunk" etc.
There seems to be a lot of confusion arising from that question. Was hoping the video would go there but it didn't
