There is a secessionist movement in NorCal[0], but as has been said before:
> Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed.
The bar for injustice is quite a bit lower than secession-inducing. If you have broad agreement in place X that they would like to live one way, and agreement among places Y and Z (who have never even been to X and would be entirely unaffected by what X does for the decision at hand) that X should live another way, then I assert Y and Z imposing their will on X is unjust, regardless of how democratic the decision was, or whether some generations-old political structure says Y and Z can do that. The people of Y and Z should recognize that they shouldn't do that.
