As another example, the U.S. is actually on its
second government, not its first.
After the American Revolution we setup a government under the "Articles of Confederation". To put it bluntly, this new government sucked and was useless.
A convention was held to suggest improvements for the Articles; they decided instead to do it over again and propose a government that could actually stand the test of time.
The framers of this new Constitution then had to convince the rest of the country to adopt this different form of government. In the process of this debate and feedback it was decided to further specify Amendments that became known as the Bill of Rights to satisfy some reluctant states.
All of this happened peacefully.
The United States of America peacefully transitioned to its second form of government on March 4, 1789.
It hasn't been all peaceful, all the time, after ratification, but it should be in my opinion. We've managed to achieve so much as a nation with non-violent resistance and protest, there's no reason not to do that here to push for transparency.
