"Does it matter to anyone if they live in a democracy?"

"How important is it to you that you speak out or speak up and that other people acknowledge your opinions and judgments about matters?"

How important that I am able to speak out is fairly important because that is what God has commanded me to do: offer terms of peace to a rebellious people before He moves in and takes over by force. 

How important that people listen/respond/agree/nod-head-in-approval is seen by my not having but a few in Claremont respond at all to the simple, "Jesus loves you." Then again, maybe it's not really simple; maybe no sentence with "Jesus" in it is simple. All humans must be heard; we are hard-wired to desire fellowship with others, and that includes communications shared, speaking and listening. All humans are hard-wired to need someone to listen. This is where we know that we are commanded to pray, and if we don't have God listening to us, pain can result. 

As for what kind of government, that is a third, also unrelated, subject. The persecuted church lives in dictatorships that vainly try to extinguish Christianity. It fails, but in the effort, the church itself is both purified and brought into such close fellowship with Christ we have-it-easies in the U.S. can't imagine their blessings. They don't talk to non-Christian humans but rarely; they talk to God all the time. 

form of government only works with smaller populations.  In a country of 300 million, an individual vote is generally useless, so there might as well not be a democracy, or democratic republic.  Add on top of that the fact that our "elected" officials put their parties and corporate sponsors before their constituents and the good of the country, and you end up with the fact that a democracy is useless, especially the kind we have.
