But it is wrong to say that you "ended the war and changed the world".
The "war" ended in 1975, long after all the protesting has slowed to a crawl. And the ending of the war mainly had to do with an exhaustion of resources amidst an economic and oil crisis, and, well, actually losing the damn thing. There is such a thing as a lost war.
Furthermore, people mainly protested not because the war was "illegal and immoral", but primarily because of the draft and how it affected them (or people they knew). Lesson learned: the government used only pro soldiers for their wars from them on, and no protests of that scale and that extend occurred again.
The baby-boomer, sixties "rebellion" was in all, a failure. It didn't "stop the war", and it didn't "change the world". It ended itself in the conformism and consumerism of the seventies and in a drug and "self-discovery" haze.
If the world has indeed changed since the 60s, it's for the worst, in the political sense, concerning society, freedom, public and international policy (technology and science have of course improved, but those two always do, since the dawn of time, and exponentially since around 1600).
Now, how about the societal change regarding the treatment of blacks? Well, that was due to their organized protests and political action (from the action around Rosa Parks to the Alabama march). And, to return to the point of Maddox, this is what the other sixties movements lacked (since SDS dissolved into irrelevance), and what we lack today.
If baby-boomers' sixties was a self-absorbed failure, there was indeed a time when Americans fought and won very significant rights. It was when they were actually organized, agitated, and fought (often to death), to gain their labour rights, regarding working conditions, eight hour day, etc. Here's an example: http://en.wikipedia.org/wiki/Ludlow_Massacre
Without political action and determination, you cannot have change. Blacking out a webpage is idiotic. "But it spreads awareness". So? What is the viewer of your webpage supposed to do with this new found awareness? Until you can answer that, it's all in vain. And writing to your congressman is idiotic. What makes him "your" congressman? Even a boycott is silly, if it's just about individuals making a choice, instead of being the co-ordinated action of some group with a minimum program and coherency.
