I don't understand how so many people can honestly favor the Quarians.
To support them is to support the genocide of a sapient species. That's my problem with them. The Quarians are a backwards society, which makes sense when you think about it. They've been stuck insdie their spaceships for years. They have little interactions with other civilizations. I say that the real world equivalent are people from small thrid-world countries; they have a government, but it's highly corrupt. Meeting the admiral board in Mass Effect 2 proved this to me. All of their leaders are apparently stupid, psychotic, ignorant, or arrogant. Even their most sensible leader, the one who supports peace, is a stuck-up worm. And his opinnion is in the minority.
The Quarians want to kill all of the Geth. They want to exterminate an entire species. I simply cannot accept that. The Geth are intelligent. They have thoughts, opinnions, and even emotions, even if they are primitve. They may be computers, but that doesn't mean they don;t deserve the same right to live that other sapitent species enjoy. The Quarians have no right to kill them. They lost the war. They were driven into exile due to their own stupidity, and they continue to dwell on the past rather than move towards the future. It's been over 300 years since they were exiled. Considering how big the galaxy is, I find it hard to believe that they can't find a single planet to live on. The reason they don't is because their leaders are incompotent fools that are determined to reclaim their homeowrld (which the Geth have equal rights to, since they were also born on it).
So in summary, the Geth are an intelligent species that has no intentions of harming the Quarians unless they provoke them. The Quarians are a fucked up species that wants to commit genocide. I think I'll side with the robots rather than the bucket heads.
