No of course not Nimpy. There still has to be a trial.
The point is, that we remove all this bullshit around cases like that of the rapist Ched Evans. He was rightly convicted because his victim was too drunk to consent. The onus was on him in that situation to see that even if she was lying there not objecting there was no way someone in that state could genuinely consent. The normal, human thing to do would be to say "Nah love you're too drunk, let's get you home," rather than to just hop on and have a go anyway.
Yet there are people including the rapist himself, who claim that he did nothing wrong.
Under the new guidance the message going out there will be that in any sexual encounter both people will need to be fully on board. It will help to dismantle this fucked-up situation where, if a man doesn't actually physically force his victim, then all other methods - drink, threats, bullying - are fair game. It sends the strong message that it is not ok for anyone to simply extract sex from another person - both people must be freely consenting, with no strings.
