Wrong.
Just as obviously the British were wrong and the revolution warranted, slavery was wrong, the Spanish American war was wrong, Vietnam was wrong, the invasion of Iraq was wrong, segregation was wrong, Prohibition was wrong, etc.
But we still have a lot to do because clearly all drug laws are wrong, all adult sex laws are wrong, immigration laws are wrong, etc.
The way you make a republic is fixing things that are wrong.
And ICE clearly is totally wrong.
They are harming people without the protection of due process.
That leads to the worst dictatorship imaginable.
