No oneever shows up for our Slacktivists United meetings.
A person who will go halfway across the country to protest racial injustice while in his own hood blacks are killing blacks.
I went to Louisiana to fight racism did any thing happen while I was gone? Not really 3 kids were shot and killed. Shit well nobody said that being a blactivist would be easy.
The brand of political or social activism that involves doing nothing meaningful whatsoever except for completely useless gestures, "discussing the issues" with people who already share your point of view, and flooding Facebook with activism posts.

That Tiffany girl who is always posting 10 times a day on Facebook about how society is controlled by anti-gay, anti-feminist, anti-immigrant, poverty-hating white guys gets drunk four nights a week on her parent's dime, and sleeps around while skipping half of the classes in her Development Studies major. She's never actually contributed to the betterment of society in any meaningful way. But pat yourself on the backtivism means she still thinks she's a better person than everyone else.
