The politics of this discussion is amazing in the sense that we can have a non-political discussion of if bacteria born on earth and growing on mars are earth life or mars life or is it morally right or wrong to transport life or "contaminate" existing cultures. However the analogy is nearly perfect if we're debating if someone born in Syria and living in England is a Syrian-lifeform or a English-lifeform and is it morally or ethically OK to "contaminate" cultures. Its interesting in that without political agitation this relatively calm and straightforward discussion is what immigration debate would look like, but we're not allowed not to be politically agitated to a certain outcome, for some reason. Or, with a hundred years of political "progress" and parallel technological advance, immigration to Mars will have a political dimension such that sterilizing in satellite-grade clean rooms and talking about contamination fears will sound like pro-nazi death camp talk to future politically active young multicultural people living on Mars and the legacy Earth.
