Government is supposed to be an entity of limited power, not an arbiter for what we should all be doing in our lives. The republic was established on over a thousand years worth of political, social, and moral philosophies. The only people who really march down the streets these days, with a couple of exceptions, are pushing out ideas that are counter to the principals of the republic and whose utterances have caused the deaths of millions of people. Remember the temptation of power: when you're asking your government to come in and dictate how to do something do you think they'll be nice and go away when its over?
Most people don't think that though. They think they have no power at all to make change. All we need is a good nationwide protest to make some change.
