If people don't have half a second of patience, how much does it take to motivate them to go to a protest, shout, march, and sometimes even risk their lives? Sure, if we're not careful, if we don't implement the right controls, social media can be used for ill. However, I'd be very careful not to generalize from results like in the OP.
There are groups of people that you wouldn't even pay attention to if it weren't for social media. There is suffering that would be invisible to the world if it weren't for social media. It is our duty to expend the small amount of energy required before assuming the worst about a freedom struggle, because sometimes solidarity is the only thing that powerless people can have.
