Hong Kong protest: Why are pro-democracy supporters staging a sit-in?
Honest question: how effective are these sorts of protests in achieving their intended goals?<p>Maybe I'm suffering from confirmation bias, but it seems all the major demonstrations in the last few decades (Tiananmen Square, Iraq War, Occupy Wall Street, post-Iranian election, etc) have sizzled out and failed.  The one exception I can think of is the anti-Proposition 8 protests, but Prop 8 was defeated in the courts through routine legal channels (ultimately culminating in the Supreme Court decision on Hollingsworth v. Perry) and it's unclear whether the protests held any sway over the rulings.
