Wanting a non-straight, transgender person of colour to join the site so they can specifically talk about 'diversity issues' while the rest of the staff can get on with talking about white dude video games like they always have is such a ridiculous insult to everyone involved.
Why is the scene necessary? The fact that this discussion thread has gone on for nearly 200 posts is the precise reason it's necessary.
Sexual violence versus not-sexual violence has been an elephant in the room for a long time, and the elephant is getting ever bigger with the rise of feminist voices to criticise the medium. Violence has long been a deeply interwoven part of video games, from Mortal Kombat and Carmageddon and the like all the way through to the modern plethora of shooters and fighters and beat-em-ups and everything else. It's not just accepted, it's become weird to not accept it. You're meant to accept Call of Duty and Grand Theft Auto, just as you're meant to accept Tarantino movies and Game of Thrones and gangsta rap. It's isn't a weird hobby, it's mainstream culture.
And that can be absolutely fine! As an adult, I trust my ability to separate fantasy and reality. I can get disgusted by what I see on the news and go on to do far, far worse things in a video game. To try and work out why this is the case is perhaps an entirely different discussion, but it's safe to say that a lot of normal, well-adjusted people do enjoy fantasy violence. I certainly enjoyed Hotline Miami 1, and I don't think that was merely in spite of its violent nature. But, Hotline Miami was more than just a shooty stabby playground. The game starts by asking you whether you like hurting people, and keeps asking - I walk back through the bloody corridors, and the 80-style synthpop melts away into something closer to static, and I do feel bad, and I do question whether this is a good thing, and the game is better for it. As much as the game is portrayed as a hyperviolent murder toy, it's hard to say it does that without knowing about it.
As a society, we need to ask ourselves how we place sexual violence amongst the other bad things we see daily in media. And for that to happen, we need to allow games to be offensive and to do things we don't like. Limiting ourselves to purely discussing sexual assault and rape in hypotheticals - how many times has the 'well the issue is not handled well by the game' argument been used in this thread without seeing anything past the first level? - and then denying the ability of games to try and tackle these issues is ridiculous. Saying that part of a game is potentially questionable is a reason to exclude it is wrong - if we do that, how on Earth are we going to answer the question of what is acceptable and what isn't if anything that gets close to the line is banned?
If we want video games to move forward as a medium, then we need games to push boundaries. We need games to tackle these issues sensitively, but we also need games to tackle issues insensitively. The medium has to grow in all directions - down as well as up - because dealing with complicated moral issues involves working out what's immoral as well as what's moral. Not liking the message in a video game isn't a reason to play it. I believe that actively seeking out things you disagree with is important, and challenging yourself against different viewpoints is an important part of becoming a better person (it's why I'm here arguing now, and probably why you're here too), and denying video games from becoming a part of that damages them. If you want video games to become more than what they are now, you should be encouraging games to push boundaries. If they fail? Then be critical, and disagree with them, knowing that their failures will spur future attempts to be better. The medium will grow up as well as down.
But if you really don't want to play a game dealing with an issue you're not comfortable with, whether you agree on their take on it or not? Then great! Don't play it. That's not a reason to say it should be removed, and that's not a reason to say it's unnecessary. The developers have already done 90% of the work in giving you the option to turn the sexual violence off. But when, instead of simply removing the scene entirely, they both defended it and took the time to make it avoidable in the face of the extensive criticism they are getting for doing so tells me it's more important to the game than pure shock value.
I'll stop rambling here, partially because I've gone way past long enough already, and partially because I'm now mostly just arguing with some imaginary strawman that wants to ban all sexual content in video games or something, which probably isn't the main goal of the Australian ratings board. But the key point I want to make is this: controversial elements like the rape scene in Hotline Miami 2 are necessary. Not for Hotline Miami 2 in particular, but for video games as a whole. Effectively banning them by not rating them is not the answer.
