I don't really understand supporting Chelsea Manning, or equating her plight with Snowden's. Snowden had a purpose and a plan, and executed it while attempting to keep people from getting hurt. Chelsea Manning lashed out at an army that didn't support her and put her in the wrong position. The military may have mistreated her, but they're still not the same thing.
Oh god, I assumed Chelsea was a separate leaker from Bradley Manning, and instantly thought "Well, she was probably acting rash" - whereas my opinion of "Bradley Manning" differed. I'm sexist. :\
Well, at least realizing your bias puts you ahead of the other 99% of people who think they aren't biased, and you can try to keep it in mind and reexamine decisions. That's what I try to do, as much as I'm capable, at least.
