Slacktivists are people who participate in tweetstorms (online) or stand outside in the streets and parks (IRL) screaming for change. These people think they can change the world by holding up cardboard signs. Slacktivism has as much chance of changing Wall Street's ways with Occupy and Anonymous signs as professional wrestling fans do of convincing the general public to "Vote -4- The Rock."
These dirty slacktivists are making it harder for me to do my grocery shopping.
Did you hear the government stopped being corrupt because 500 people RT'd some slacktivism tweet by @YourAnonNews?
