It's important to realize that lack of public outcry/protests, or even public approval, does not necessarily mean that they support it. All my Chinese Tsinghua/Peking friends (20+) find it horrifying, yet many of them will find ways to show support for both this and other government propaganda, because they realize doing so will be beneficial for their future (even those who don't realize the government is building a profile based on everything they've ever said can still find value in sharing the propaganda because their friends, family, coworkers, teachers and bosses will see that they're "patriots").

Why should they risk their future/life fighting for something they don't believe they have the ability to change? It's like asking, why weren't the Germans resisting Hitler's government? It's easier said than done, heck, I even feel worried about posting these comments even though I don't live in China anymore and have no intention of ever going back.
