Hotdrop, they are offering constructive criticism of what you've presented. If you are not open to such critique, you probably shouldn't post it here. Much like them, I'm going to offer a bit of constructive criticism, but it has nothing to do with your material. Your response would be much easier to read if you used paragraphs, instead of blending it all into one, big one.

Lastly, any truly democratic society doesn't abide having a large standing military when there's no war going on. I could go on at length to explain, but that'd definitely stray into the "no politics" area of the rules.
Essentially, your Outersphere League flies in the face of all known conventions, and not only stretches believability, but pretty much breaks it.
