Anytime there is oppression you can tie it to black people. I mean they could have done an alien thing and how aliens had to fight for their rights also. The game still has a lot of good moments, and a lot of people liked the game.
Claiming well it's just androids are black people is completely missing the point of the game.
Yea, but the game specifically alludes to many things which happened to black people in America (EX: the back of the bus thing). Like I said, it's not subtle in the slightest. More accurately it tries to be subtle and hide it's allegory behind the paper-thin illusion of being androids without bothering to explore what that really means.
Let's take the very first bit for example. Right at the start of the game we are presented with a hostage situation in which the player character needs to talk down a robot who has taken a child hostage. The 'ideal' ending has the player succeeding in this and talking the robot down, convincing him to trust you, before the police guns the robot down once the child is safe. This makes no sense if this was about what it means to be human or anything else. If the robot really was a robot, even one starting to attain sentience, then the whole scene should have been presented differently. Instead it's designed specifically to only make sense if you make the connection that the robot is already akin to a human and it is the prejudice of the humans that is the problem especially since the robot is portrayed in a wholly sympathetic, or at least relatable, light. This is made especially clear when the one person he chose to spare was the child whom had treated him like a human and a friend. A move that only makes sense if the robot is already sentient.
Had they wanted to handle this scene better and make it clear it was about the measure of a person instead of a hamfisted racism allegory they should have picked a robot that couldn't be mistaken for human acting legitimately on the fritz and the whole problem being that the developing free will was conflicting with its preprogrammed instructions. It didn't want to kill the family, it was a legitimate accident, but now it also doesn't want to die but assumes violence is the only deterrent. It would be even better if this was not shown and was only uncovered later in the story. That way the player wouldn't immediately realize the whole plot from the getgo.
Two games that had similar things did this better. In Neir your first contact with the robots is a bought of explicitly hostile conflict with a blatantly dangerous foe. Even afterwards the enemies will be robots as well so even if you somehow accepted that they were sentient from the getgo you'll remain on-guard around them. This way the player is actively encouraged to treat them as enemies and a danger and the contemplation as to if they are sentient beings can be put off until the assumption that they are not is sufficiently strong to challenge the notion.
Likewise in Megaman the robots that rebel are hostile and need to be dealt with, free will or not. However robot life is never devalued in the series and it's shown that devaluing it is what leads to such conflicts as the robot masters are frequently discarded robots whom have outlived their usefulness. We even see this eventually come to a head with the decision to not revive humanity in legends 2 (I think that was the one) because doing so would mean destroying synthetic life.
Even in Mass Effect we spend the first game battling the Geth. We know that the geth are dangerous beings who drove the quarians off their homeworld and remain occasional enemies throughout the franchise. However we also meet not only a Geth who is our ally but ED-I; both of whom are sentient. We can easily see the harm that synthetic life can do via the Geth and reapers, but at no point is it suggested that it's because they're synthetic. In fact the quarians assumption that there would be a geth uprising is what lead to the whole problem in the first place.
If you really think about it the message of DBH simply doesn't make sense on any level. Most people would be over the moon to have a robot friend. Even if they didn't treat them the same as a living being they CERTAINLY wouldn't treat them like slaves unless they were the sort of person whom would also treat humans like slaves anyways. Likewise most humans are well aware that things like racism and slavery is wrong, especially in America where the narrative is practically blared through loudspeakers. So a game which deals with such a thing has no choice but to be a played out and predictable in it's story and message. It's like listening to a story in Sunday School. No matter what happens you know the story will somehow relate back to the Bible and Jesus and try to deliver a moral in some way even before it begins.
