Dissent is always an important part of the Democratic process and should be protected. Protecting dissent should not entail ignoring those who refuse to follow the laws established by the representatives of the several states.
California routinely rejects US laws while promoting a hostile environment towards the US government. One example is the establishment of so-called sanctuary cities.
Article IV of the US Constitution guarantees to every state in this union a republican form of government and protection against domestic violence. To ignore California's blatant disregard of US laws undermines the republican form of government guaranteed by the Constitution and threatens the security of other states.
The time has come to end this by contracting the Union by one state - California.
