The reason that this sort of sexually aggressive behaviour is controversial is that it is so obviously an area where the acceptability and ethics of how to act are pretty ambiguous. While it might be easy to condemn the more obvious violations of people’s bodies without permission, it becomes a much more complicated matter when drink or drugs are involved (and drinks and drugs are not the only factors that influence people to behave in ways that they might later regret). Where is one to draw the line between “legitimate” seduction and unacceptable behaviour? If there is an apparently unaccountable desire to protect this particular predator, and other predators generally, it’s because so many people, including both men and women, prize the freedom to indulge in drunken mistakes, and might not perceive the behaviour of the predator to be sufficiently different to that which they regard as normal. The law is itself ambiguous — for it relies on the subjective evaluation of whether or not somebody was too intoxicated to legitimately make a decision — so there’s no common agreed line.
