Since this is the best thought out of the freaking 5 responses I got to my D-9 comment, I'll respond to this one (wow, people love that movie). Alright, I suppose I can accept your explanation, but then that would just change my opinion from this being a "plot hole" to just being a pretty shitty story, and then my biggest question would be how did all the intelligent aliens die? But my biggest problem I have with that response is that so many people praise D-9 because of its "deeper meaning" and social commentary on apartheid - and how is this conveyed? By using a bunch of idiotic alien drones as the substitute for the actual human beings who suffered in the past. Wow, how profound.
Which is why the best way to think of it is to simply accept that the aliens are normal, intelligent creatures, and then turn your question on its head and ask why the "plot hole" exists in real life that so many rational, intelligent humans put up with horrific conditions in refugee camps throughout history, and rarely rise up in organized resistance to overthrow their "oppressors"? The very fact that you used the word oppressor there is an indication that you may be missing important elements of the D-9 story.
Also, to counter the idea that the aliens had access to advanced technology, whereas modern human refugees don't, remember that all of their technology requires a power source that they no longer have ready access to. Many of the weapons would have worked for a short time, but once out of fuel/energy/ammo, what then? Any alien belligerence would have been a very short-lived movement, in other words.
