Well first of all I am not going to read your full length novel of a post. But I understand that you obviously wanted to get your views across.
As far as I'm concerned, playing a game that has slavery, drug dealing, murder, smuggling, etc... isn't going to change the way I think about such things. It is not going to make me think that such things are ok. Nor I doubt it will change anyone else's views.
I do understand where you are coming from, but I think you may be over thinking this.
Remember that this is just a game after all. If you took out all the 'bad' parts of the game then what would be left? Just mining and exploration.
As strong as your views are, coming on here to talk about it won't change anything. The game will continue as it currently is. Of course, no one is forcing you to play ED either, so if you don't like the slavery side of it, then the solution is simple. Don't play it.
Also, how far do you go with this. Partition for all games to not show slavery? Ban films that show it? Burn books that talk about it?
And what about the other 'bad' aspects of this game and others (murder, drugs, kidnap). Should all that be banned from games, books and films too?
I do understand your views somewhat, but coming on here to preach about it won't change a thing.
