Which responsibility of american citizens is the most important why

The most important responsibility of American citizens is voting.

There is nothing that can be compared to the importance of voting, as this defines the future of the American nation, voting is a way of exposing your truth and helping your country in a real way.

I would have to say the most important responsibility of American citizen is abiding by the rules that America was founded on. Not judging people by their race, ethnics or gender. Equality throughout the workforce and homeowning. The lack of justice in America. That's what American citizens along with the government need to work on.

observing traffic laws in exchange for driving on the highway.
