Protests happen more and more online now. Angry about something? Make a humorous meme about it and watch the whole world laugh at it, dissolving & disarming the power of the thing you're angry about has.
I'd say the opposite - it dissipates the anger and make people feel like they accomplished something, all the while the problem still exists and is getting formally entrenched via policy and legislation. But hey, we joked about it online, so all is well?
I don't have a specific problem in mind, BTW, just observing that the actual impact of online content is minimal. "Actions speak louder than words" is doubly true with online content.
