Why do protests against the government fizzle out and die? The structure of the U.S. government is set in such a way that they will always fail. People can organize and cause a lot of noise to raise "awareness" but it is destined to fail, to not even come close to its desired outcome. Those who make the argument, "Nothing will be accomplished if we don't try" cannot grasp the fact that it's over before you try. I was in the protest crowd for a long time, and I slowly but surely learned that the change we were demanding is impossible in this system of government. This realization was frustrating, but I couldn't deny the obvious truth. Optimists say that nothing is impossible, I guess it makes them feel good, but when it comes to something like protesting the government you have to be a realist. The truth is in the results. Politicians in Washington are not influenced by people standing on the street waving signs, they vote for whatever will make them richer and more powerful. I am certainly no fan of this corrupt "democracy" which is structured so the people can have a voice, but it doesn't mean that your heard. The politicians may listen to you, but they do not hear you.
So, stand outside with your signs if you want to, no one is stopping you, but don't get your hopes up.
