You are happy where you are.
And that's what you go to a war over, and get thousands killed? Shame on you!
The proper response is to write a scathing letter in the local newspaper, or go to the pub, get drunk and complain to your pint until it appears to start listening. Not to start shooting at people.
I mean last I hear on the subject they weren't federation citizens any more.
That never happened. In "Journey's End", a bunch of colonists who definitely weren't Maquis abandoned their UFP citizenship and were never heard of again. In the remaining episodes describing the colonists at the Cardassian border, a bunch of colonists started shooting at stuff but never had the guts to stop being UFP citizens and reaping the benefits; when this murderous scum was finally wiped out in "Blaze of Glory", Eddington expressed anguish that they had been on the verge of declaring independence from the UFP, but never got around to it.
