Murder is among the leading causes of death for women, but particularly pregnant women. This is only small compared to homicide counts against young black men, but it should also be remembered that hate crimes are not the primary motivator in those numbers, either. To suggest that pregnant women are much less a target of violence and homicide because of their pregnancy than a young black man is a target because of his race alone is to be wrong.
Of course, there is a problem with this argument in that racism is a profound source of poverty and desperation, and both of those situations create environments in which murders and other crimes occur. The bigots discovered long ago that if you keep people oppressed enough that they begin to behave like animals, they are able to tell themselves that those people are like animals, continue to oppress them, and continue to hide from the fact that their racism is indirectly murder.
This is true among highly educated people, oddly enough. My grandfather, the late chief justice for the court of Delaware, went to his grave believing that black people caused crime because most of the crimes he reviewed (the gritty sort) were committed by blacks against blacks, not realizing or at least not expressing the idea that poverty causes crime and racism causes poverty among blacks.
As far as the mockup, presented out of context, the player does not understand why he is having wrenches thrown at him. He unwittingly becomes the homosexual protagonist who is not by any means deserving of such a treatment. Presented in context, he becomes so knowledgeably. Whatever anger the player feels in that situation is directed at the unseen adversary - it is impossible to know where the wrenches are coming from aka it is impossible to know who is a danger to you as a homosexual until it becomes an immediate problem. I stand by the piece as - intentionally or not - promoting empathy for the targets of an arbitrary hatred, be it homosexuality or be it something else equally irrelevant to their rights to a pain-free existence, due to the assignment of roles.
If they were reversed, say, you were to win by beating homosexuals, it would be much more of a debate between whether it was good or bad. it would be significantly more profound, as a game, in that empowerment demands decision making which demands a consideration of the subject - it forces people to strongly consider whether they are comfortable with being a bigot. The success of the game would be measured by the number of people who refuse to play it, because that refusal demonstrates an understanding that the hatred is wrong which is what the game and the film are trying to convey.
