Freedom isn't moving away from your oppressor, for two reasons.
1) If you aren't free, you can't move.
We've got an oppressive government, and a repressive moral majority. The result? People who aren't free -- be they black people, gay people, disabled people, native americans...whoever -- don't have the capital or the time or the opportunity to just up and leave.
2) Liberty is having freedom WHERE YOU ARE. If you can't be free where you are, you aren't free.
