It really is incredible how most guys just don't get why something like this is sexist. It goes a long way towards explaining why casual, mindless sexism still exists.
The trailer is about a large group of personality-and-identity-free scantily clad women being beaten, choked, and shot to death by a large well-dressed white man. They even provide a scene of him getting himself ready in the bathroom, in order to humanize him. The women are, of course, pure fap material and largely interchangeable. They are dressed in ways to make their profession totally impractical and nothing they do makes any logical sense, so it's a bit like violence porno.
If you cannot see the problem with the glorification of ruthless violence committed on sexualized, dehumanized women, then you are a little behind on your societal sensitivity, my friend.
Yes, a lot of games involve of killing hordes of men. Yes, a lot of those men tend to be faceless drones served up for murder. But ask yourself this: how many of them are depicted in such a way as to give you an erection while you're killing them?
It's dumb, it's insulting, and really, we *should* be way past this. The fact that we clearly are *not* is the problem, gents. Get yourself some class and get with the zeitgeist before it runs you over.
